Answer:
x = y = 104°
Step-by-step explanation:
The sum of the interior angles = 360°
The opposite angles x and y are congruent , that is y = x , then
92 + 60 + x + x = 360
152 + 2x = 360 ( subtract 152 from both sides )
2x = 208 ( divide both sides by 2 )
x = 104
Then
x = y = 104°
<em>A = 80°</em>
<em>B = 10°</em>
- Step-by-step explanation:
<em>complementary angle => </em>
<em>=> A + B = 90°</em>
<em>A = 8B</em>
<em />
<em>8B + B = 90°</em>
<em>9B = 90°</em>
<em>B = 90° : 9</em>
<em>B = 10°</em>
<em>A = 8B</em>
<em>A = 8×10°</em>
<em>A = 80°</em>
Answer:
The expression which will result in difference of two squares is:
(–7x + 4)·(–7x – 4)
Step-by-step explanation:
We know that the formula of the type:
(a-b)(a+b)=a²-b²
i.e. it is a difference of two square quantities. (a^2 and b^2)
since,
a= -7x , b=4
(-7x+4)(-7x-4)= (-7x)² - (4)²
=(7x)² - 4²
So the expression is a difference of two square quantities:
(7x)² and (4)²
Hence the answer is (–7x + 4)·(–7x – 4)....
