Answer:
B, x=5
Step-by-step explanation:
Both triangles are similar with a ratio of 22.5/9
so using that an equation can be created like this,
= 
If simplified, 22.9(x + 4.44) = 23.5(9)
22.5x + 99 = 211.5
22.5x = 112.5
<u><em>x = 5</em></u>
Answer:
7.1 cm
Step-by-step explanation:
Let s represent the side length of the square. The Pythagorean theorem tells you the relationship to the diagonal length is ...
(10 cm)² = s² +s² . . . . the sum of the squares of the legs is the square of the hypotenuse
100 cm² = 2s² . . . . . . simplify
50 cm² = s² . . . . . . . . divide by 2
√(50) cm = s ≈ 7.1 cm . . . . . take the square root
The length of a side of the square to the nearest tenth is 7.1 cm.
Answer:
400 to 5 in simplest form
Step-by-step explanation:
Find the GCD (or HCF) of numerator and denominator. GCD of 400 and 5 is 5.
400 ÷ 55 ÷ 5.
Reduced fraction: 801. Therefore, 400/5 simplified is 80/1.
3x+x+20 = 180
4x = 180-20
4x = 160
x = 40
×+20+3x+2x+38+C=360
40+20+3×40+2×40+38+C=360
40+20+120+80+38+C=360
298+C=360
C=360-298
C =62°
