The answer is 100,000,000+3,000,000+700,000+20,000+7,000+400+90+5.
Answer:
angle 3 = 61
angle 4 = 119
angle 6 = 61
angle 7 = 119
Step-by-step explanation:
there are a few ways you could look at this
first, each angle that is diagonal from eachother is going to be equal so 1 is the same as 3, 2 is the same as 4 etc
also each line going across has to be 180° so if angel 1 was 175 then angle 2 has to be 5 so when you combine them it becomes 180
if you look at the sizes some are bigger than the others, because you're given angle 1 = 61 then all the other small angles would be 61 too, and 180 - 61 = 119 so the all the big ones have to be 119
if this confused u more I'm sorry lol let me know if this helped

Answer:
15/24
Step-by-step explanation:
15 of 24 would be 15/24
a) Due to you have a right triangle, in order to calculate the value of d, use the Pythagorean thorem:
![d=\sqrt[]{(60m)^2+(20m)^2}=\sqrt[]{4000m^2}\approx63.2m](https://tex.z-dn.net/?f=d%3D%5Csqrt%5B%5D%7B%2860m%29%5E2%2B%2820m%29%5E2%7D%3D%5Csqrt%5B%5D%7B4000m%5E2%7D%5Capprox63.2m)
Hence, the distance d is approximately 63.2m
b) To find the angle of elevation, use the sine function of θ, as follow:
![\begin{gathered} \sin \theta=\frac{opposite}{hypotenuse}=\frac{20m}{60m}=\frac{1}{3} \\ \theta=\sin ^{-1}(\frac{1}{3})\approx19.8 \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20%5Csin%20%5Ctheta%3D%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D%3D%5Cfrac%7B20m%7D%7B60m%7D%3D%5Cfrac%7B1%7D%7B3%7D%20%5C%5C%20%5Ctheta%3D%5Csin%20%5E%7B-1%7D%28%5Cfrac%7B1%7D%7B3%7D%29%5Capprox19.8%20%5Cend%7Bgathered%7D)
Hence, the angle of elevation is approximately 19.8°
