Answer:
<em>The old photo frame is still rectangular</em>
Step-by-step explanation:
<u>Rectangles</u>
The rectangle shape can be identified because it has 4 internal angles of 90° each. The diagonal forms with two adjacent sides a right triangle where the Pythagora's Theorem must stand. Being a and b the length of the sides of the rectangle and d the diagonal, then:

Vince's photo frame has dimensions of 8 inches and 6 inches, with a diagonal of 10 inches. If the above condition is met, then the frame is still rectangular.
Calculating:



Since the condition is met, the old photo frame is still rectangular
Answer:
A = 110 degrees.
Step-by-step explanation:
< A and < B are same side angles so their values add up to 180 degrees, so:
5x + 20 + 9x - 92 = 180
14x - 72 = 180
14x = 252
x = 18.
So m A = 5(18) + 20
= 110 DEGREES.
Answer:
a.
Step-by-step explanation:
4x+y=20 multiplied by (-4) gives you -16x-4y=-80
