Answer:
y = -13/16
Step-by-step explanation:
<u>Given:</u>
0.8y+0.25= -0.4
<u>To Find:</u>
Solve for y
<u>Solution:</u>
Multiply both sides by 100

Simplify

Subtract 25 from both sides

Simplify

Divide both sides by 80

Simplify

Thus, y = -13/16
or in decimal form it equal y = -0.8125

4. all for angles need to equal 360
90 +90 + 42 = 222
360-222 = 138
y = 138 degrees
x - 42 degrees
6. x = arctan(8/4) = 63.43 degrees ( round as needed)
y = 16 / tan(63) = 8.15 ( round as needed)
