Part 1:all triangles have a measure of 180 degrees
so, 3(x+2)+35+52=180
add 35 and 52; 3(x+2) +87=180
subtract 87 from both sides; 3(x+2)= 93
divide both sides by 3; x+2=31
subtract both sides by 2; x=29
Part 2: since 3(x+2) =93, angle C is 93 degrees
Answer:
4x² - 20x + 25
Step-by-step explanation:
(2x-5)² means (2x-5)(2x-5)
Expand the brackets.
1. do 2x times 2x = 4x²
2. do 2x times -5 = -10x
3. -5 times 2x = -10x
4. -5 times -5 = 25
Altogether it is 4x² - 10x - 10x + 25
This simplifies to 4x² -20x + 25.
