Answer:
<h2>C. x = 6</h2>
Step-by-step explanation
since we have a right triangle then we can apply the Pythagorean theorem:
x² + 8² =10²
⇒ x² = 10² - 8²
⇒ x² = 36
⇒ x² = 6²
⇒ x = 6 (because x is positive)
Answer:
x = 15, 72 degrees
Step-by-step explanation:
4x + 12 + 108 = 180
4x + 120 = 180
4x (+ 120 - 120) = 180 - 120
4x = 60
4x/4 = 60/4
x = 15
4x + 12
4(15) + 12
60 + 12
72 degrees
Answer:
(f+g)(x)=2^x-5x+1 and
(f-g)(x)=2^x-x-1
Step-by-step explanation:
(f+g)(x)=2^x-3x+1-2x
=2^x-5x+1
(f-g)(x)=2^x-3x-1+2x2x
=2^x-x-1
