Answer:
t = 89°
Step-by-step explanation:
- total interior angle of triangle is 180°
angle 1 is (t-46), angle 2 is (t), angle 3 is (180-(t+43))
summing them:
(t-46)+(t)+(180-(t+43)) = 180°
t -46 + t + 180 -t -43 = 180°
t + 91° = 180°
t = 180° - 91°
t = 89°
Answer:
(-1,0)
Step-by-step explanation:
Point B is located one position to the left on the x-axis resulting in a negative x-value in the coordinate pair, and Point B is located 0 units up on the graph resulting in a y-value of 0. Therefore, (-1,0) are the coordinates.
Answer:
314 m²
Step-by-step explanation:
the surface area of a sphere (As) is
As = 4×pi×r²
our radius r (half of the diameter) here is 5m.
As = 4×3.14×5² = 4×3.14×25 = 100×3.14 = 314 m²
Plug it in.
y = -1, y1 = 1
x = 3, x1 = 1
-1 - 1 = m( 3 - 1)
-2 = 2m
m = -1
The slope is -1
y = -x +b
-1 = -3 +b
b = 2
The equation is y = -x + 2
Hope this helps.
