When the triangle is a right triangle, you can use the Pythagorean theorem. The formula would be
c^2 = a^2 + b^2
If a = 21 and c=29, thus
b^2 = c^2 - a^2
b^2 = 29^2 - 21^2
b^2 = 400
b = square root (400)
b = 20 units.
Thus, the answer is <span>D) B = 400</span>
Answer:
64 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the length of the side )
Given
area = 16, then
s² = 16 ( take the square root of both sides )
s = 
= 4 , thus
V = 4³ = 4 × 4 × 4 = 16 × 4 = 64 in³
Answer: There are 20 years in a score. The year he is talking about is 1776
Step-by-step explanation:
Answer :
a + 1/4b
6/a + b/4
ab- 17
b/2 + 4
b + 1/a
5a - 6
Step-by-step explanation:
5a - 6 = 9
b/2 + 4 = 8
ab - 17 = 7
6/a + b/4 = 4
b + 1/a = 8.5
a + 1/4b = 3.03125
