Answer:
First problem: 9; second problem: 12
Step-by-step explanation:
1 27
----- * ------ = 27/3 = 9
3 1
1 84
----- * ------ = 84/7 = 12
7 1
1/3x27= 9
1/7x84= 12
H= 10
Hypotenuse formula if you have the other 2 sides.
Yes it is.
Just multiply everything by 2.
angle x equals 25
130 + 25 = 155
180 - 155 = 25
Triangles always add up to 180°
