B 9.2 in will be your answer for the test
Answer:
13 units
Step-by-step explanation:
The legs of an isosceles trapezoid are congruent, then
x + 8 = 48 - 7x ( add 7x to both sides )
8x + 8 = 48 ( subtract 8 from both sides )
8x = 40 ( divide both sides by 8 )
x = 5
Then
leg = x + 8 = 5 + 8 = 13
Answer:
c = 8.7 inches
Step-by-step explanation:
a^2 + b^2 = c^2
Substitute in the known values for a and b (the order doesn't matter):
(4.8)^2 + (7.3)^2 = c^2
multiply 4.8 times itself, 7.3 times itself:
23.04 + 53.29 = c^2
76.33 = c^2
Now find the square root of both sides of the equation (square root of c^2 = c):
8.736= c
It says round to the nearest tenth, so c = 8.7 inches
Y = 2x + 2
The slope must stay the same since they are parallel and the new point would be the y intercept.
Answer:
13, 13√3, 26
Step-by-step explanation:
30 60 90 right triangle
Ratio of short leg : long leg : hypo = a : a√3 : 2a
Given short leg = 13, so long leg = 13√3 and hypo = 13 * 2 = 26
Answer:
13, 13√3, 26
