Answer:
129
Step-by-step explanation:
8^2 + 9 (12/3 x 2) -7 Parentheses first 12 : 3 is the same as 12/3
8^2 + 9 (4x2)-7 Parentheses:
8^2 + 9 (8) - 7 Exponent 8 x 8:
64 + 9(8) - 7 Multiply:
64 + 72- 7 Add :
136 - 7 Subtract:
129
The answer is 129.

The sum of all interior angles of a quadrilateral is always 360
A parallelogram is a quadrilateral, so the answer is 360 degree so
Answer:
<em>x</em> = 2
Step-by-step explanation:
Given data: The two triangles in the diagram are similar.
AB = 10 cm, AC = <em>x</em> cm, AE = 15 cm, AD = 3 cm
By similar triangles property,
Do cross multiply
⇒ 10 × 3 = 15 × <em>x
</em>
⇒ 30 = 15<em>x</em>
⇒ 30 ÷15 = 15<em>x</em> ÷ 15 (By division property of equality)
⇒ <em>x</em> = 2
Hence, the possible value for<em> </em><em>x</em> is 2.
Answer:
Step-by-step explanation:
Angles with measures and (or pmore precisely, vertical angle to angle 8x-21) are supplementary (add up to 180°).
Converse to same-side interior angles theorem states that If two same-side interior angles are supplementary, then l║p.
So, to prove that lines l and p are parallel, you have to show that angles and are supplementary.
Thus,
