Answer:
C=13
Step-by-step explanation:
Pythagorean theorem
a^2 + b^2=c^2
a squared plus b squared equals c squared
Answer:
Step-by-step explanation:
Complementary angles add up to 90
6x + 29 + x + 5 = 90
6x + x + 29 + 5 = 90
7x + 34 = 90
7x = 90 - 34 {Subtract 34 from both sides}
7x = 56
x = 56/6 {Divide both sides by 6}
x = 8
∠A = 6x + 29
= 6*8 + 29
= 48 + 29
∠A = 77°
Answer:
What do you need help with?
Step-by-step explanation:
One of the unknown angles (let's called it n) has a complement (meaning their sum adds up to 90 degrees) and the other angle is 8 times the unknown angle (8n)
With all this information, you should have the equation:
n + 8n = 90
To solve, combine like terms to get:
9n = 90
Divide by 9 on both sides to isolate the variable n.
n = 10
Now we plug back in to find our angle measurements. The first angle, n, is 10 degrees. The second angle, 8n, is 8 * 10 which is 80; the second angle is 80 degrees.
