Answer:
C)x=6
Step-by-step explanation:
x+4=10
x+4−4=10−4
x=6
Answer:
x = 25
<B = 120 degrees
<C = 30 degrees
Step-by-step explanation:
Total angle measure of a triangle - 180 degrees
Add all the angles together to find the value of x
30 + 4x + 20 + x + 5 = 180
55 + 5x = 180
55 - 55 + 5x = 180 - 55
5x = 125

x = 25
<B = 4(25) + 20
<B = 100 + 20
<B = 120
<C = 25 + 5
<C = 30
Step-by-step explanation:
Let the digit at tens place of a two digits number be X
The place value of X = 10×X = 10X
The units digit = 5 more than its tens digit
= X+5
The place value of units digit
= (X+5)×1
= X+5
Now
The two digits number
= 10X+X+5
⇛ 11X+5
Therefore ,The two digits number = 11X+5.
