Answer:
A
Step-by-step explanation:
a^2 + 144^2 = 145^2
a^2 + 20736 = 21025
a^2 = 289
a = sqrt(289)
38,320 (for positive scientific notation you move the decimal to the right how ever many places, so move the decimal 4 places to the right in this case)
The answer is D. (3 times 4 times 5 is 60)
Answer: 253°F
Step-by-step explanation:
Given the following :
Temperature in Antarctica = - 121 Fahrenheit
Temperature in Sahara desert = 132 Fahrenheit
Number of degrees in which Sahara desert is warmer than Antarctica :
(temperature in Sahara desert - temperature in Antarctica)
= ( 132°F - (-121°F))
= (132°F + 121°F)
= 253°F
Sahara Desert is 253°F warmer
Inscribed Quadrilateral Theorem says that quadrilateral can be inscribed in a circle if and only if the opposite angles are supplementary.
That means
∠C+∠A=180⁰
∠B+∠D=180⁰
So, ∠C+∠A=180⁰ ---->84 + x = 180 ------> x=180-84=96⁰.
Answer: x=96⁰.
