Answer:
x = y = 15
Step-by-step explanation:
Using the sine ratio and the exact value
sin45° =
, then
sin45° =
=
=
( cross- multiply )
2x = 30
( divide both sides by 2 )
x = 15
The triangle is isosceles (45- 45- 90) , then 2 legs are congruent, so
y = x = 15
3(19-4)=2(19)+7
distribute the 3
57-12=38+7
45=45
Step-by-step explanation:
Im not sure ut it looks like 3x over 3x would cancel eachother out.
Answer:
53.5 and 36.5
The Sum of two angles is 90 degree
Is called complementary angle
53.5 + 36.5 =90
53.5 - 36.5 =17
