Answer:
21°
Step-by-step explanation:
We can prove these two triangles congruent by the HL (Hypotenuse-Leg) theorem. Then, we know that m<YQR is congruent to m<PQY. We can then use their given values to form an equation.
5x+6=16x-27
Continue to solve . . .
33 = 11x
x=3
Therefore, we can plug this value of 3 into the expression for the value of m<YQR, and you will get
(16 x 3) - 27, which is equal to 21°.
Answer:
[45tan(82°)+123] meters
A is correct
Step-by-step explanation:
You are standing 45 meters from the base of the Empire State Building.
You estimate that the angle of elevation to the top of the 86th floor(the observatory) is 82°.
If the total height of the building is another 123 meters above the 86th floor.
OB = 45 m , ∠O= 82°
In Δ OBA, ∠B = 90°
Top of the building, T at 123 m from A
Total height of building = BA + AT
Hence, The height of building from ground is [45tan82°+123] meters
Answer:
160 nickels, 80 pennies
Step-by-step explanation:
160 nickels = $8
80 pennies = $0.80
$8 + $0.80 = $8.80
This is PEMDAS as well as order of operations and or parentheses, exponents, multiplication, division, addition, and subtraction. Multiplication and division go together, so you do whichever one comes first. Same goes to addition and subtraction. A way to remember the order is Please Excuse My Dear Aunt Sally.
This is how you solve.
6^2 = 6 * 6 = 36
3^2 = 3 * 3 = 9
so 36 + 9 = 45
this correct, pls mark brainliest
