c
Step-by-step explanation:
all you gotta do is move the figure up 3 squares, and to the right 3 squares, the way I do this is one point at a time
Answer:
12.
m∠ACB = 180° - 58° - 78° = 44°
m∠DCE = 180° - 85° - 60° = 35°
m∠BCD = 180° - 44° - 35° = 101°
13.
Base on the picture, we know that:
x° + 2x° + 3x° = 180°
6x° = 180°
x° = 180° ÷ 6 = 30°
=> m∠K = 2x° = 2 × 30° = 60°
=> m∠L = 3x° = 3 × 30° = 90°
=> m∠KML = x° = 30°
m∠LMN = 60° + 90° = 150°
We can see here that there are 2 triangular bases on the prism.
To calculate the area of a triangle, we multiply the base and the height and then divide by 2.
A = 8 x 6 /2
A = 48/2
A = 24
Hope it helps!
According to the statement lines, r and s are parallel, then when a line intercepts both lines the angles formed are going to be the same.
Then x is at the same position as 156°.
Answer:
120°
Step-by-step explanation:
<U + <T = 180
or, 6x-6+9x+21=180
or, 15x=165
or, x=11
so, <T = 9×11+21 = 120
