چکیده
One triangle has angles measuring A, β−α and 90. The other triangle has angles measuring B, α− β, and 90. The two right angles are placed back to back with the two triangles having the same height. Using algebra and substitution, we got something that is similar to the proof but a couple of variables are switched, meaning that there is more work to do. I wonder if this method can be used though because it limits the values for the measures of the angles in the triangle.

Key principles for breeding spring-and-autumn using silkworm varieties: from our experience of breeding 873?874
The successfully breeding of the hybrids 873?874 had settled the problem that the yield was not uniform to the silk quality in silkworm varieties. In this paper, we illuminated the key technology, principle, hints and methods for selection in breeding spring-and-autumn rearing silkworm varieties were analyzed using the procedure of breeding the hybrid of 873?874 as example.
متن کاملThe Study of Poisoning Whit Mushroom and Toxic Plants (Tattore and Ricinus Communis) Incidence in Patients Who Admitted in Shohadaie Ashaier and Madani Hospitals in the Spring and Summer of 2007
Bachground: Toxic plants are an important reason for poisoning. The responsible plants are variable in different geographic spots. Some areas such as Lorestan province have more variety in herbal plants because of geographic condition. Because of high poisoning incidence with toxic plants and mushroom, we assessed the incidence of poisoning with mushroom and toxic plants (Tattore and Ricinus ...
متن کاملA numerical simulation of orthodontic tooth movement produced by a canine retraction spring.
Tooth movements produced by a canine retraction spring were calculated. Although a gable bend and an anti-rotational bend were incorporated into the spring, the canine tipped and rotated initially. Retraction force decreased and moment-to-force ratio increased after the spring legs closed. Then, the initial tipping and rotation began to be corrected. As a result, the canine moved almost bodily ...
متن کاملPregnancy rates of frozen embryos recovered during winter and summer in Sistani cows
During spring, summer and winter seasons, Sistani donor cows, with normal reproductive status, were superovulated and embryos were recovered non-surgically on day 7. Grade A blastocyst embryos were either transferred fresh (spring) or frozen (summer and winter). Recovered embryos during summer and winter were exposed to glycerol and frozen using conventional method. During spring season, recipi...
متن کاملDoes fumagillin control the recently detected invasive parasite Nosema ceranae in western honey bees (Apis mellifera)?
Western honey bee (Apis mellifera) colonies in Nova Scotia, Canada were sampled in spring and late summer 2007 to evaluate efficacy of fumagillin dicyclohexylammonium (hereafter, fumagillin) against Nosema ceranae. Colonies treated with fumagillin in September 2006 (n=94) had significantly lower Nosema intensity in spring 2007 than did colonies that received no treatment (n=51), but by late sum...
متن کاملComposition and intra-annual variation of the macroinfauna in the estuarine zone of the Pando Stream (Uruguay).
We studied the temporal patterns of macroinfaunal distribution in the estuarine portion of Pando Stream, Uruguay. We found a very low number of species and a high dominance of the polychaete Heteromastus similis. There were clear seasonal patterns in abundance with almost all species peaking in autumn, coinciding with the periods of higher salinity. Minimal values were found in winter and sprin...
