4 times 1 = 4 so the top one would be 4/12, but i can't help with the rest because i don't understand what they are asking for
The area of the right triangular tabletop is calculated through the equation,
A = 0.5(L₁)(L₂)
The area, as stated above, is equal to 400 in². Substituting the known values to the equation above,
400 = 0.5(16 in)(L₂)
The value of L₂ is equal to 50 inches. Thus, the second length is equal to 50 inches.
The correct answer would be -3/8 or in decimal form -0.375 :)
Answer:
Step-by-step explanation:
Angles 3, 4, and 5 are supplementary to each other, meaning that all of them added together equal 180. Therefore, to solve for x:
x + 18 + x + 15 + 4x + 3 = 180 and
6x + 36 = 180 and
6x = 144 so
x = 24
Angles 1 and 3 are vertical angles, so they are congruent, meaning they both have the exact same angle measure. If angle 3 measures, x + 18, so does angle 1. If x = 24, then angle 1 = 24 + 18 which is 42 degrees.
That also answered part c. Angles 1 and 3 are not complementary, they are vertical.
