If the measure of angle A = 40 and B is a complement of A, then the measure of angle B = 50. If C is a supplement of B, then the measure of angle C = 130.
the measure of angle A = 40
the measure of angle B = 50
the measure of angle C = 130
Hope this helps!
Answer:
x = 63.43 , 243.43 degrees for 0 <x < 360.
Step-by-step explanation:
tan x = 2
The angle in the first quadrant whose tangent is 2 is x = 63.43 degrees.
If we consider the range 0 < x < 360 degrees tan x is positive in the third quadrant so x is also 180 + 63.43 = 243.43 degrees.
Answer:
It would be 1.026
Step-by-step explanation:
When you are doing percents, you usually divide. So 153.9 divded by 150 would give you 1.026.
Answer:the number of black tiles that Todd used is 27
Step-by-step explanation:
Let x represent the number of black tiles that Todd used.
Todd has 21 white tiles and some black tiles to make a mosaic. Each tile has an area of 3 square. It means that the total area of the white tiles is 21 × 3 = 63 cm^2
The total area of the white tiles is x × 3 = 3x cm^2
The mosaic has a total area of 144 Square centimeters. It means that
3x + 63 = 144
3x = 144 - 63 = 81
x = 81/3 = 27
