Answer:
Correct choices are a, b, e
Step-by-step explanation:
As per diagram, the circles are equal.
<u>Since the distance AB is the radius of both circles:</u>
- AB = AC = BC = BD = AD = r
<u>So the answer choices:</u>
a. AC = BC
b. AC = BD
C. CD = AB
- Incorrect. Half of CD is the leg of 30-60-90 triangle and is equal to r√3/2, so CD = AB√3
d. ABCD is a square
- Incorrect. ACBD is rhombus
e. ABD is an equilateral triangle
- Correct, all three sides are equal to r
f. CD = AB + AB
He used 7 pints all together because there at 2 cups in each pint and 4 pints in a half a gallon.
Answer:
Part A: 1148
Part B: 545
Step-by-step explanation:
Part A: 2x + 58
Part B: x
2x + 58 + x = 1693
3x + 58 = 1693
3x = 1635
x = 545
Part A: 2x + 58 = 2(545) + 58 = 1148
Part B: x = 545
1. The two angles add up to 180°.
2. You can create an equation because of this:
2x - 3 + 7x + 21 = 180
9x + 18 = 180
- 18
9x = 162
÷ 9
x = 18
3. <KMP is equal to <YMA because they are vertically opposite, so you can substitute in the value of x to find it.
(7 × 18) + 21
126 + 21 = 147
answer = 147°
4. The complement of an angle is the value that makes it add up to 90°, so first we need to find <KMA:
(2 × 18) - 3
36 - 3 = 33°
90 - 33 = 57
answer = 57°
I hope this helps!
