The diagram tells you that the triangle is an isosceles triangle. From this we know that angles B and C will be equal to each other. To find what the angle measures are, we are going to set the two given expressions equal to each other, solve for x, and the plug x back in to get the two angle measures.

$2x+10=3x-5\\10=x-5\\15=x$

Now we are going to plug x back into each expression to solve for angles B and C.

Angle B

$2x+10$ ⇒ $2(15)+10=40$

Angle C

$3x-5$ ⇒ $3(15)-5=40$

Both angles B and C are equal to 40°

Lock # 1 Dr. E. Quation lost 25 grams of silver in a heist he attempted to pull-off at the Hyesan Mine in North Korea. That was

WITCHER [35]

Answer: 20 grams

Step-by-step explanation:

Hi, to answer this question we have to write an equation:

The amount of grams of silver he lost at the Holdong mine heist(x) plus 5 , is equal to the amount of grams of silver he lost in the Hysean mine heist. (25)

Mathematically speaking:

x+5=25

Solving for x

x = 25-5

x = 20 grams
