A right triangle has an angle that is 50∘. What is the measure of the missing angle?
1 answer:
Answer:
40 degrees.
Step-by-step explanation:
right triangle means an angle that is 90 degrees.
so the measure of the missing angle :
90+50+x = 180(for sum of all angles is 180 degree) (and we are assuming missing angle as x)
therefore x= 180-(90+50).
that is 180-140.
there fore missing angle measure is 40 defrees

The answer would be 19.25
25 = -16t^2 + 50t + 4
16t^2 - 50t + 21 = 0
16t^2 - 8t - 42t + 21 = 0
8t(2t - 1) - 21(2t - 1) = 0
(8t - 21)(2t - 1) = 0
8t - 21 = 0 or 2t - 1 = 0
t = 21/8 or t = 1/2
t = 2.625 or t = 0.5

Answer:
9/5=x
Step-by-step explanation:
-3x+ 18=7x
-3x+3x+ 18=7x +3x
18=10x
18/10=10x/10
9/5=x
