X=leahs cousins age

2x+x=36

add the x's together.

3x=36

you then divide 3x by 3 and 36 by three.

36/3=12

leah's cousin is 12.

36-12=24

leah is 24.

hope this helps xx

angle A and angle B are complementary angles. If m angle A = (4x – 28)° And angle B = (4x - 8)°, then find the measure of A.

Flura [38]

Complementary angles have a submission of 90 degrees thus :

$angle \: \: A + angle \: \: B = 90°$

$(4x - 28)° + (4x - 8)° = 90°$

$4x + 4x - 28 - 8 = 90$

Collect like terms

$8x - 36 = 90$

Add both sides 36

$8x - 36 + 36 = 90 + 36$

$8x = 126$

Divide both sides by 8

$\frac{8x}{8} = \frac{126}{8} \\$

$x = 15.75$

_____________________________________________

Now let's find the measure of A :

$A = 4x - 28$

$A = 4 \times (15.75) - 28$

$A = 63 - 28$

$A = 35°$

And we're done...
