<em>Answer:</em>
( B ) x = 6.5
<em>Step-by-step explanation:</em>
We know that all the angles of a triangle equal 180 when added together. So lets make an equation for this question.
(10x-10) + (10x+8) + 8x = 180
I just took all the angles and added them together to make 180. Now solve for x.
10x - 10 + 10x + 8 + 8x = 180 <em>(combined like terms)</em>
28x -2 = 180 <em>(added 2 to both sides)</em>
28x = 182 <em>(divided both sides by 28)</em>
x = 6.5
The area is the product of length and width, which is to say that the length and width are factors of the area.
Assuming the dimensions are integers, you want factors of 84 that differ by 5.
... 84 = 1×84 = 2×42 = 3×28 = 4×21 = 6×14 = 7×12
The last of these pairs differ by 5, so ...
- the length is 12 inches
- the width is 7 inches.
Answer:
m<M = 50°
Step-by-step explanation:
m<M +m<P +m<V=180° (sum of the interior angles of the triangle)
x+78+52°=180°
=>x+130= 180°
=>x=180°-130°
=>x= 50°

11.7 degrees approximated to 12 degrees
