Answer:
14 yd
Step-by-step explanation:
The cross section is a triangle with a height of 19 and a base of x
Area of a triangle = bh/2
133 = 19x/2
266 = 19x
x = 14
Answer:
x = 5
Step-by-step explanation:
Just use the Pythagorean Triangle:
13^2 - 12^2 = x^2
x^2 = 25
x = 5
Answer:
Step-by-step explanation:
Sum of angles in a Δ= 180°
x + 2x +3x = 180
6x= 180
Divide both sides by 6
x=30
sooo x= 1×30= 30, 2x= 2×30= 60, 3x=3×30= 90
since 30+60+90= 180
∴the angles are 30°,60° and 90° respectively
