I’ll be happy to help!
Since a right angle is equal to 90 degrees, we can add the 67+90 which equals 157, so since a triangle is equal to 180, we can subtract 180-157.
180-157= 23
The answer for x is 23!
Answer:
6/15 because when you divide it , it's 0.4 ( bigger than the other ones)
Answer:
first one is 23
second is 20
Step-by-step explanation:
Answer:
y = 2 ( x + 3 ) 2 − 4
Step-by-step explanation:
Use the form a x 2 + b x + c , to find the values of a , b , and c . a = 2 , b = 12 , c = 14 Consider the vertex form of a parabola. a ( x + d ) 2 + e Substitute the values of a and b into the formula d = b 2 a . d = 12 2 ( 2 ) Simplify the right side. d = 3 Find the value of e using the formula e = c − b 2 4 a . e = − 4 Substitute the values of a , d , and e into the vertex form a ( x + d ) 2 + e . 2 ( x + 3 ) 2 − 4 Set y equal to the new right side. y = 2 ( x + 3 ) 2 − 4
