1: b=9
2: a= 24
3: c=17
4: b=10
Use a^2 + b^2 = c^2 to answer.
1: 12^2 (144) + b = 15^2 (225)
225-144 = 81
Square root 81 = 9
2: a + 49 = 625
625-49=576
Square root 576 = 24
3: 64 + 225 = 289
Square root 289 = 17
4: 576 + b = 676
676-576 = 100
Square root 100 = 10
We know that
if sin A=cos B
then
angle A and angle B are complementary angles
so
A+B=90 degrees
in this problem
(x+34)+(2x+20)=90-------> 3x+54=90----> 3x=90-54-----> x=36/3----> x=12°
the answer is
the value of x is 12 degrees

Answer:
4x(2x - 1)
Step-by-step explanation:
8x² - 4x ← factor out 4x from each term
= 4x(2x - 1)
I believe you would Add like terms so 4x^2-4x-3
