(Unless the rectangle is a square.) And the angles formed by the intersection are not always the same measure (size). Opposite central angles are the same size (they are congruent.)
Simply find the difference between the intercept and axis of symmetry then apply it to the other side
-1 › 3 = 4
so
3 + 4 = 7
Answer:
Step-by-step explanation:
LCM of 4 and 8 = 8
Answer:
<A=56.64
<B=114.99
<C=8.33
Step-by-step explanation:
let angle C be x
8x-10+3x+90+x=180°[sum of inside the triangle is 180°]
12x+80=180
12x=180-80
x=100/12
x=8.33
now putting the value of x
angle C is 8.33
angle A is 56.64
angle B is 114.99
Approximately divide the region into 10 vertical strips, each with width of about 1. Next, estimate the y-coordinates of the top and bottom of each strip of this region. For example, the 1st strip stretches from approx. 2 1/4 at the bottom to approx. 2 1/4 at the top, so the total length of this strip is about 4 1/2. Since the area is (width)(height), and the width is approx. 1, the area is (4 1/2)(1) = 4 1/2.
2. Approximate the area of each of the remaining 9 strips.
3. Sum up your 10 approx. areas.
