Step-by-step explanation:
ΔACX is an isosceles triangle, so ∠AXC = ∠XAC. We'll call the measure of this angle x°.
∠AXC and ∠BXC are supplementary, so ∠AXC + ∠BXC = 180. That means ∠BXC = 180 − x.
ΔBXC is an isosceles triangle, so ∠XBC = ∠XCB. We'll call the measure of this angle y°.
Angles of a triangle add up to 180, so:
y + y + (180 − x) = 180
2y = x
y = x/2
∠ACX and ∠XCB are complementary, so ∠ACX + ∠XCB = 90.
x + y = 90
x + x/2 = 90
3/2 x = 90
x = 60
Therefore, ∠AXC = ∠XAC = 60°.
A perfect square is what u get when u multiply 2 of the same numbers together.
For example : 2 * 2 = 4.....4 is a perfect square
3 * 3 = 9...9 is a perfect square
4 * 4 = 16....16 is a perfect square
2 cannot be a perfect square because u cant multiply anything by itself that equals 2.
so ur perfect square numbers are : 1,4,9,25,36,81,144,225,400
2 1/3 + 1/15
= 2+ (1/3+ 1/15)
= 2+ (5/15+ 1/15) (common denominator)
= 2+ 6/15
= 2+ 2/5
= 2 2/5
The final answer is 2 2/5 cups~
Step-by-step explanation:
The exponent of a number describes how many times to multiply the number by itself.
<u>Multiply;</u>
3 is B
4 is D
I can figure out 5, Im kinda bad at plotting.
