Answer:
x=39
y=28
Step-by-step explanation:
this is isosceles triangle
from the picture
angle A equals to angle B
so
34=x-5
39=x
so A and B are 34 degree each
so angle C is 180-2(34)
then 180-2(34)=4y
180-68=4y
112=4y
28=y
Multiply the √49 by √4 - this will give you √196 over 4
√196 = 14
therefore you have 14/4
divide each by 2 to simplify
this gives you 7/2 <-- your final answer
Answer:
x = 45
Step-by-step explanation:
The average is calculated as
average = 
here the average = 50 , thus
= 50
Multiply both sides by 4
36 + 44 + 75 + x = 200
155 + x = 200 ( subtract 155 from both sides )
x = 45
Answer:
D
Step-by-step explanation:
21 + 4 = 25 x 4 = 100 and 100 is 84 + 16
