Answer:
x = -9
y = 5
Step-by-step explanation:
<u> </u><u> </u><u>7y</u><u> </u><u>-</u><u> </u><u>2x</u><u> </u><u> </u><u>=</u><u> </u><u>5</u><u>3</u><u> </u> +
-6x = 54
x = -9
(-7y) - 4(-9) = 1
(-7y) + 36 = 1
-7y = -35
y = 5
Answer:
Step-by-step explanation:
CA and CB are both opposite equal 90 degree angles so are equal so we can say
8x-12=4x
4x-12=0
4x=12
x=3, since CA=4x
CA=4(3)=12

Answer:
The smaller angle is 20 degrees.
Step-by-step explanation:
A triangle's interior angles must have a sum of 180 degrees. Hence the two acute angles must have a sum of 180-90=90 degrees.
Say that the angles have 2x and 7x length:
2x+7x=90
9x=90
x=10
Hence the acute angles have degrees 2*10=20, 7*10=70.
The smaller angle is 20 degrees.
