Answer:
∠ D = 127°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ D is an exterior angle of the triangle , then
∠ D = 85° + 42° = 127°
Since the table has 8 sides that all have the same length then multiply 4 by 8 so the answer is 32
Answer:
x=1
Step-by-step explanation:
8+2x-7x=5(x-3)-2(6x-8)
8+2x+7x=5x-15-12x+16
8+15-16=5x-12x-3x-7x
23-16=-7x-3x-7x
17=-17x
x=1
Answer:
I have my correct answers in the photo so just read from that :) <3
To solve for the surface area of a sphere, the formula is 4*pi*r^2. Since we are using 3.14 instead of pi, the formula becomes 4*3.14*r^2. To solve, all we have to do is substitute in the radius for r and solve it like a normal question.
SA=4*3.14*r^2
SA=4*3.14*6^2
SA=452.16
Since we used 3.14 instead of pi, we have to say this is an approximate answer. This means the surface area of this sphere is 452.16 square inches.
