Answer:
theta = 180 -(A +B)
Step-by-step explanation:
The sum of the angles of a triangle is 180
theta + A + B = 180
solve for theta
Subtract ( A + B) from each side
theta +A+B -(A +B) = 180 -(A +B)
theta = 180 -(A +B)
You use Pythagorean theorem to solve it and you get 18.3. Just look at the picture to see how i solved it
Answer:
B √8
Step-by-step explanation:
Equation of a circle is:
(x − h)² + (y − k)² = r²
where (h, k) is the center and r is the radius.
The center of the circle is (1, 6).
(x − 1)² + (y − 6)² = r²
The circle passes through the point (-1, 8).
(-1 − 1)² + (8 − 6)² = r²
4 + 4 = r²
r = √8
