The sum of the measures of angle x and angle y is 90. if the measure of angle x is 30 less than twice the measure of angle y, what is the measure of angle x?

The measure of angle x is 50 degrees.

SOLUTION:

Given, the sum of the measures of angle x and angle y is 90.  

Then,

The measure of angle x is 30 less than twice the measure of angle y,  

Then,

We have to find the measure of angle x

So, now substitute (2) in (1)

Then,

Then,

Therefore, the measure is 50 degrees

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
