Equation practice with angle addition​

Mathematics
1 answer:
TEA [102]3 years ago
7 0

Answer:

∠MON = 57°

Step-by-step explanation:

∠MON = ∠LON - ∠LOM

(2x + 33°) = 113° - (3x + 20°)

2x + 33° = 113° - 3x - 20°

2x + 3x = 113° - 20° - 33°

5x = 60°

x = \frac{60}{5} \\\\x = 12

then

∠MON  = 2x + 33°

∠MON = 2(12) + 33°

∠MON  = 24 + 33°

∠MON = 57°

Calculate the area of the figure below using the following information:
vekshin1

Answer:

106.5 square units.

Step-by-step explanation:

See the attached diagram.

The pentagon ABCDE consists of three triangles namely Δ ABC, Δ ACD, and Δ ADE when we join the diagonals AC and AD.

So, Area of Pentagon ABCDE = Area of  Δ ABC + Area of Δ ACD + Area of triangle Δ ADE.

⇒ Area of Pentagon ABCDE = (31.8 + 39.2 + 35.5) = 106.5 square units. (Answer)

What is the remainder when a^3-4 is divided by a+2?
Harman [31]

Answer:

-12

Step-by-step explanation:

Use synthetic division to find the remainder:

a + 2 yields the synthetic division divisor -2.  The four coefficients of a^3 - 4 are {1, 0, 0, -4}.  Setting up synthetic division results in:

-2   /   1    0    0    -4

              -2    4     -8

     -------------------------

         1     -2    4    -12

The remainder is -12.  This is also the value of a^3 - 4 when a = -2.

The time, t in seconds that it takes a car to travel a quarter-mile when starting from a full stop can be estimated by using the
sammy [17]

The computation of the power shows that Natasha was right as the value gotten is 295hp.

<h3>How to calculate power?</h3>

From the information given, t is given as 5.825 to the cube root of w/p.

In this case, the value of p will be:

p = w/t³(5.823)³

p = 3590(5.823)³ / (13.4)³

p = 708828.13/2406.104

p = 295hp

In conclusion, Natasha was correct.
