Answer:
A = 53 degree
90-37 = 53 degree
As the triangle is a right angle triangle we see complimentary to the other angles and as all angles in a triangle equal 180, we see the other two which compliment this.
Step-by-step explanation:
Step-by-step explanation:
Given,
y=2x=,z=3x,r=4x
Now,
x+y+z+r=360°(complete turn)
x+2x+3x+4x=360°(given)
10x=360°
x=360°/10
x=36°
Hence,
x=36°
y=2x=2×36°=72°
z=3x=3×36°=108°
r=4x=4×36°=144°
7/x = 5/y
Can be changed to:
5x = 7y
So, x = (7/5)y and
y = (5/7)x
