Answer:
69.4 degrees.
Step-by-step explanation:
Complementary angles add up to 90 degrees so we have the equation:
4x + 3 + x + 4 = 90
5x + 7 = 90
5x = 83
x = 16.6
The larger angle = 4x + 3
= 4(16.6) + 3
= 69.4 degrees (answer).
Answer:
x = -1
y = -9
Step-by-step explanation:
<u>A</u><u>d</u><u>d</u><u> </u><u>each linear equation:</u>
Sum: 5x = -5
<u>Divide each side by </u><u>5</u><u>:</u>
Quotient: x = -1.
<u>Substitute x = </u><u>-</u><u>1</u><u> into the </u><u>first</u><u> equation:</u>
4(-1) - y = 5
<u>Solve</u><u>:</u>
-4 - y = 5
<u>Add 4 to both sides of the equation:</u>
-y = 9
y = -9.
<u>Check with the second equation:</u>
-1 + -9 = -10.
Correct.
To find the value of x we follow this:
3x+17=14
Take away 17 from both sides
3x=-3
Then divide by 3
x=-1
