Answer: 
Step-by-step explanation:
By definition, the sum of the interior angles of a triangle is 180 degrees.
Based on this, you need to set up the following equation:
The next steo is to solve for "x" in order to find its value. This is:
You can observe in the picture of the triangle ABC given in the exercise, that:
Therefore, you must substitute the value of "x" into that equation and then evaluate, in order to find the measure of the angle B. This is:
Answer:
s+6+s+6+s+s+2s=102, s=18
Step-by-step explanation:
The perimeter is the sum of the side lengths, so
the equation is s+6+s+6+s+s+2s=102.
Answer:
A percentage or percent for short is a fraction; a fraction that always has the denominator as 100. Because the denominator of a percent is always a 100, no matter what the numerator is, we replace 100 with the percent symbol % after the number. By definition, for any number x, x% = x100.
Step-by-step explanation:
a) 35w+55-10w = 25w+55
28w+75-5w+12 = 23w +87
b) 25w+55 + 23w +87
=48w+142
they will be short by 2(24w+71)
c) 50w+25 = 25(2w+1)
answer: =98w+167
