Answer:
c
Step-by-step explanation:
Answer:
The slope of line A is C. 2
Step-by-step explanation:
You can check the slope by dividing the rise (how many units up) and the run (how many units across). This line has a rise of rise of 4 and a run of 2. Diving 4 by 2 gives you a slope of 2.
Answer:
40.56 ft
Step-by-step explanation:
The perimeter is the sum of the lengths of the "sides" of this figure. Starting from the left side and working clockwise, the sum is ...
P = left side (8 ft) + top side (10 ft) + semicircle (1/2×8 ft×π) + bottom side (10 ft)
= 28 ft + 4π ft
= (28 +12.56) ft
P = 40.56 ft
So, angles A and B added together is 130° which makes the whole angle = 180°-130°=50°
The answer is 180° because it is a supplementary angle and all supplementary angles equal 180° so, all the angles added makes 180°
