6z - 12 + 4 = 10
6z -8 = 10
6z = 18
z = 3
The answer id 12 meters.divide -2x^2+20x+48 by 2 to get x alone and then umbrella
Answer:
3.23
Step-by-step explanation:
Answer:
85 degrees
Step-by-step explanation:
the sum of supplementary angles=180
155+ angle in the triangle=180
angle=180-155
angle=25 degrees
the sum of angles of triangle=180
25+60+x=180
85+x(inside triangle)=180
x=180-85
x=95
angle with (?):
the sum of supplementary angles=180
95+(?)=180
(?)=180-95
(?)=85 (An exterior angle of a triangle is equal to the sum of the opposite interior angles)
