Answer:

SIN(a) = G/H = 5/13

A^2 + G^2 = H^2 --> A = √(H^2 - G^2) = √(13^2 - 5^2) = 12

COS(a) = A/H = 12/13

Can someone please help me out with this! Im struggling a lot with this!<br> x=1 <br> y=-5

Alla [95]

Answer: See attached.

Step-by-step explanation:

When we have a simple x = a equation, the line will be vertical since all y values of that function/equation are equal to a. In this case, that is 1.

Similar thing for a y = b equation. The line will be horizontal since all x values of that function/equation are equal to b. In this case, that is -5.

MariettaO [177]

Answer:

x = 25

Step-by-step explanation:

Since ∠ A = ∠ B then the triangle is isosceles and AC = BC , that is

4x - 30 = 2x + 20 ( subtract 2x from both sides )

2x - 30 = 20 ( add 30 to both sides )

2x = 50 ( divide both sides by 2 )

x = 25
