Y+y-3 is the expression need to find the triangle's area
Answer:
x = 27
y = 29
Step-by-step explanation:
Refer to the diagram shown below.
Given:
m∠A = 19°
c = 15
By definition,
sin A = a/c
Therefore
a = c*sin A = 15*sin(19°) = 4.8835
cos A = b/c
Therefore
b = c*cos A = 15*cos(19°) =14.1828
Answer:
The lengths are 4.88, 14.18, and 15.00 (nearest hundredth)
-68hen you enter an equation into the calculator, the calculator will begin by expanding (simplifying)
the problem.
C. 20x = 200 because an equation always has an equal sign and other three are expressions because it doesn't have any signs, hoped this helped:)
