Answer:
1. 23
2. 8
Step-by-step explanation:
1. 180-157 = 23
2. 15²+x²=(9+x)²
225 +x²=81+18x +x²
225-81=18x
144 = 18x
x = 144/18 = 8
HL(c) = a² + b² = c²
c = 9
c² = 18
√18= 4.24264068712
So! since this triangle is a "45° 45° 90°"
The two short legs are equivalent
meaning each side equals; <span>4.24264068712</span>
QUE :
75 - [5 + 3 of (25 - 2 × 10)]
= 75 - [5 + 3 of ( 25 - 20)]
= 75 - [5 + 3 of 5]
= 75 - [5 + 15]
= 75 - 20
= 55

Answer:
I just did for your previous posting.
3 Is B. The formula for finding the area of a circle is A= r(to the second power) times Pi. The radius is 6, so you must do 6 to the second power which is 6 times 6. That is 36. Your answer will be 36 pi.
