Answer:
∠ 1 = 142°
Step-by-step explanation:
∠ 1 and 38° form a straight angle and are supplementary, thus
∠ 1 + 38° = 180° ( subtract 38° from both sides )
∠ 1 = 142°
Equal. 4 and 5/5 is just 4 + 1, which is 5. 20/4 is also 5.
Answer:
350 cm2
Step-by-step explanation:
use the formula 2h ( l+b)
Answer:
y = -4x+14
Step-by-step explanation:
First find the slope
m = (y2-y1)/(x2-x1)
m = (2-10)/(3-1)
=-8/2
= -4
The slope intercept form of a line is
y = mx+b where m is the slope and b is the y intercept
y = -4x+b
Substitute a point into the equation
10 = -4(1)+b
Add 4 to each side
14 = b
y = -4x+14
