Answer:
Answer is 12
Step-by-step explanation:
180-94=86
4x + ? =86
not 24 because that is over
not 117 because it is acute
not 35 because it is acute
so the answer is 12
4x is acute
Two ways:
Step-by-step explanation:
1. First way. Using the trig unit circle.
tan (pi - x) = - tan x
2. Second way. Apply the identity:
tan(a-b)=tan a- tan b/ 1 - tan a×tan b
tan (π - x)= tan π - tanx/1 - tan(π)×tanx
Since tan (pi) = 0, therefor:
tan(π−x)=−tanx
Answer:
In geometry, the reflexive property of congruence states that an angle, line segment, or shape is always congruent to itself. If ∠ A \angle A ∠A is an angle, then. \angle A \cong \angle A. ∠A≅∠A.
...
Reflexive property in proofs.
StatementsReasons3. a c = b c ac=bc ac=bc3. Substitution property of equality
Answer:
30
Step-by-step explanation:
Buying apples and bananas with $10
5 pounds of bananas so
5 x .80 = $4
5 pounds of apples so
5 x 1.40 = $7
$7 + $4 = $11
she only has $10
$11 - $10 = - 1,00
so no. she will not recieve any change because she doesnt havew enough money
