Answer:
number 1 is 5 inches
Step-by-step explanation:
it fits in the 15 inches 3 times.
5*3=15
You need to know what type of triangle it is , all your triangles are right angles that means that they are 90° so you just need to subtract the number that its given from 90° ex
the first problem you just have to do this
21° - 90° = 79 °
so x = 79°
So, You cross multiply and get 56x=244(100). Simplify and you get 56x=24400. Divide each side by 56 and you get 435.71. 56% of about 435.71 is 244.
