Answer: the answer is B
Step-by-step explanation:
Answer:
28
Step-by-step explanation:
25+26+27+28=106
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°
Remember
![x^ \frac{m}{n}= \sqrt[n]{x^m}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7Bm%7D%7Bn%7D%3D%20%5Csqrt%5Bn%5D%7Bx%5Em%7D%20%20)
