Answer:
C
Step-by-step explanation:
Since the triangle is right with hypotenuse QR
Use Pythagoras' identity to solve for QR
The square on the hypotenuse is equal to the sum of the squares on the other two sides, that is
QR² = 8² + (8
)²
= 64 + 192
= 256 ( take the square root of both sides )
QR = 
= 16
Answer: x=26
Step-by-step explanation:
1. Write the equation 2x-5+4x-1+30=180 because all triangle angles add up to 180°
2. Simplify the equation by combining like terms. Write the equation as 6x+24=180
3. Subtract 24 from both sides. Write the equation as 6x=156.
4. Divide 156/6 and get 26. That is your answer (x=26).
The corrects answers are B and D for this one.
Since you divide the same side for both the the rectangles on both parts and if the division statements are equaled, then they are similar.
For example;
Answer B.
50 / 10 = 5
and
30 / 6 = 5
Answer D.
7.5 / 2.5 = 3
and
4.5 / 1.5 = 3
Since they both equal the same for both of the rectangles for the answers individually, they are similar polygon rectangles.
Hope this helps!
