Find angle a2 which is 40 degrees because it is parallel to angle c.
Find the total of d1 and d2.
total of d1 and d2: 180 - 40 - 40 = 100 degrees
Find d1 and d2 separately.
100 divided by 2 = 50 degrees
Use d1 to find b1 to find total of a1 and a2.
b1 is parallel to d1 so b1 = 50 degrees
a1 and a2 = 180 - 50 - 50 = 80 degrees
a1 = 80 divided by 2 = 40
Since a1 and c1 are parallel due to alternate angles, c1 is 40 degrees
Find b2 now which requires you to do total - minus all angles in the triangle with angle b2.
180 - 40 - 50 - 40 = 50 degrees (angle b2)
AOB has b1 and a1.
40 + 50 = 90 degrees (a1 + b1 = AOB)
The answer is 90 degrees
The term that best describes two events that together include all outcomes in the sample space is complementary.
Answer:
$900
Step-by-step explanation:
first you need to find the unit rate by dividing 270 by 3, which the answer would be 90. now we have $90. now we need to find the amount for 10 people, and we already have the unit rate. with the 90 dollars, we multiply it by 10. your final answer would but $900 for 10 people. hope this helps!

Insert data and it will calculate the (MAD).
Answer:
Area of triangle = 1/2 × base × height
Step-by-step explanation:
The two big traingles have same dimensions..
its height = 24ft
base=32 ft
so area of one big traingle = 1/2 × 32 × 24
= 384
similarly area of another big traingle = 384 as it has same dimensions.
now one small traingle... both have same dimension
its base =7
height=24
its area = 1/2 × 7 ×24
= 84
another small traingle area similarly = 84
Total area = 384+ 384 +84+ 84
=936 units ...
