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
1 1/2-5/8 = 7/8 rope is left
Answer:
70 degrees.
Step-by-step explanation:
Hello!
It says that this triangle is a right triangle. That means one angle is 90°. Since there are 180° in a triangle, all we have to do is subtract 90 + 20 from 180.
90 + 20 = 110
180 - 110 = 70.
So the medium angle is 70°.
Hope this helps!
Since they are adjacent complementary angles, that means angle TUV and angle VUW add to equal 90°. Since angle TUV is 80°, you subtract 80 from 90, which gives you 10°. So, this means angle VUW is 10°.
