CAN SOMEONE PLEASE HELP ME WITH THIS PLEASE!!

y = 120

Step-by-step explanation:

The sum of the angles of a triangle = 180°

87+33+x=180

120+x=180

x=60

In a straight angle, the measure is 180°

60+y=180

y=120

Hope that helps, tell me if you need more help

×=60 and y=120

Step-by-step explanation:

The interior angles of a triangle add up to 180 ° so you subtract the angles you know and get x, for Y and X it is a supplementary angle that measures 180 ° you subtract x which is 60 ° and you get y = 120 °

15

step-by-step explanation:

we are given the following expression and we are to solve it and find the product:

-13 × (-5)

solving the given expression in the standard order of solving a mathematical expression, beginning with the opening of brackets and then multiplying the terms and changing their signs.

-3 × -5 = 15 (answer is positive because when negative is multiplied with negative, it gives a positive answer)

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
