4x + 2y = 56. 5x + y = 34. y = -5x + 34. 4x + 2(-5x + 34) =56. 4x -10x + 68 = 56. -6x = -12. x=2. 4(2) +2y = 56. 8+2y = 56. 2y = 48. y = 24.

x=2, y=24.

Find the missing angles
lora16 [44]

Let's find a.

We are given a right angle which is 90° and an angle marked by "a" next to it. We know that when they are added together, they make a supplementary angle so we can make a equationa and solve.

90 + a = 180

a = 90°

Let's find b.

By looking at the graph, we can tell that the angle "b" and the angle that measures 163° is the same. Thus, b = 163°.

Let's find c.

Using what we did for a, we can solve for c using what we got for b. We can make an equation and solve.

163 + b = 180

c = 27°

Let's find d.

Using the angle that measures 70°, we can solve it like we did with a and c.

70 + d = 180

d = 110°

Let's find e.

Now that we know what d equals, we know that d and e make a supplmentary angle. So, make an equation and solve.

110 + e = 180

e = 70°

Best of Luck!
