<span>In this expression, you must first arrange all the elements, so that you could see where to unknowns, and where not. Then you need to add or subtract like terms. After this we get the result as below.

-7 - 8y + 1 - 2y = ?

-8y - 2y - 7 + 1 = -10y -6

What is the value of y? Enter your answer in the box. y = An isosceles triangle with vertices labeled A, B, and C. Side B C is t

masha68 [24]

Answer:

$y = 5$

Step-by-step explanation:

Given:

An isosceles triangle ABC with AB = AC.

∠A = $(4y+10)\°$

∠B = $75\°$

∠C = $(3x)\°$

We know that, for an isosceles triangle, the angles opposite equal sides are also equal to each other.

Therefore, ∠B = ∠C

⇒ $75 = 3x$

⇒ $x=\frac{75}{3}=25$

∴ ∠C = $3\times 25=75$ °

Now, the sum of all the interior angles of a triangle is always 180°.

$\angle A + \angle B + \angle C=180\\(4y+10)+75+75=180\\4y+10+150=180\\4y+160=180\\4y=180-160\\4y=20\\y=\frac{20}{4}=5$

Therefore, the value of 'y' is 5.
