Ответ:
2a + a = 90°
3a = 90°
a = 30°
2a = 60°
large angle = 60°
smaller angle = 30°
Ответ:
1. in this exercise, we need to simplify the expression:
the square root of a division equals the division of the square root sof the factors, thus:
and the square root of a product equals the product of the square roots of the factors as well, therefore:
2. we need to simplify the expression:
by applying distributive property we have:
3. for a right triangle we have:
squaring each side of the equation:
we have:
