Answer:
C. 53°
Step-by-step explanation:
<l + 96° = 149° <exterior angle of a triangle is equal to the sum of two opposite interior angles>
< l = 149° - 96°
<l = 53°

Answer:
a) 49
b) 84
c) (B) -- always odd
Step-by-step explanation:
We observe that the number of square tiles is the square of the pattern number. The number of circular tiles is 1 more than the pattern number on each side of the square.
square tiles = n²
circular tiles = 4(n +1)
__
<h3>a) </h3>
7² = 49 square tiles are needed for pattern number 7.
__
<h3>b)</h3>
4(20+1) = 84 circular tiles are needed for pattern number 20.
__
<h3>c) </h3>
The parity of the number of square tiles matches the parity of the pattern number. (The square of a number has the same parity as the number.) Since 4 is a factor in the number of circular tiles, its parity is always even. The parity of the total number of tiles will match the parity of the pattern number.
When the pattern number is odd, the total number of tiles will always be odd. (B)
V = 1/2B*H*L
V = 12*35*40/2
V= 16,800/2
V= 8,400
The volume of the right prism is B) 8,400
Answer:
24
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
4x-10+2x+15+x=180
7x+5=180
7x=175
x=25
So 2x+15=65 and 4x-10=90.
90+65+25=180
So your triangle is a right triangle.
