Sin(angle) = opposite/hypotenuse
sin(H) = GF/HF
sin(H) = 5/13
arcsin(sin(H)) = arcsin(5/13)
H = 22.61986 ... which is approximate
H = 23 degrees ... round to the nearest whole number
Answer is choice A
Answer:
48
Step-by-step explanation:
Vertical angles are congruent
7x - 22 = 4x + 8 {Add 22 to both sides}
7x = 4x + 8 + 22
7x = 4x + 30 { subtract 4x from both sides}
7x - 4x = 30
3x = 30
x = 30/3
x = 10
4x + 8 = 4*10 + 8
= 40 + 8
= 48
7x - 22 = 7*10 - 22
= 70 - 22
= 48
Answer:
-45/7
Step-by-step explanation:
1. make -7 into fraction form. -7/1
2. find a common denominator. there isn't one, so just use 7. multiply -7/1 x 7/7.
3. you should get -49/7. add 4/7 to it and you get -45/7
