Angle sum of a triangle = 180°
Type of Triangle: Isosceles.
Therefore, 2 of the angles are equivalent.
2x = 50
2 ( 25 ) = 50
50 = 50
Meaning that the sum of the 2 angles is 100°.
( 5y + 10 ) + 2x + 50 = 180
5y = 180 - 100 - 10
5y = 70
y = 70 / 5
y = 14°
ANSWER:
y = 14°
Answer:
Equation is 42t
So,
t=12
According to equation
Put value of t
=42(12)
=504
So 2nd option is correct.
Answer:
5-2+1-3=1
Step-by-step explanation:
If x be one angle then its complementary angle = 90-x
therefore we can write the equation:-
x - (90- x) = 84.8
2x -90 = 84.8
2x = 174.8
x = 174.8 / 2 = 87.4 degrees
and its complement = 90 - 87.4 = 2.6 degrees
