<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. Here we have no expressions for ∠CBD and ∠ABC, so I'll assume:

\angle CBD=15x-24 \\ \\ \angle ABC=20x+40

We know that the measure of ∠CBD is 45% of the measure of ∠ABC, then:

\angle CBD = 45\%(\angle ABC) \\ \\ \\ Or: \\ \\ \angle CBD = 0.45(\angle ABC) \\ \\ \\ Substituting \ expressions: \\ \\ 15x-24=0.45(20x+40) \\ \\ \\ Solving \ for \ x: \\ \\ 15x-24=9x+18 \\ \\  15x-9x=24+18 \\ \\ 6x=42 \\ \\ x=\frac{42}{6} \\ \\ \boxed{x=7}

jenyasd209 [6]

Answer:

Sentence structure needs to simple, standalone, Grammarly justified and able enough to convey the writer thoughts and feelings clearly

It is just like the skeleton of a write up and hence its framework needs to be clear and able enough to express the real sense. The structure of sentence needs to be complete with adequate grammar and punctuations. A good sentence must be able to express a complete idea  on its own.

What set of three numbers could represent the lengths of the side of a right triangle?
klemol [59]

Answer:

C.) 5, 12, 13

Step-by-step explanation:

In a right triangle, the sum of the squares of the two shorter sides must equal the square of the longest side (Pythagoras).

a² + b² = c²

We can test each set of numbers to see which one fits.

A.) 8² +  12² =   16²

    64 + 144 = 256

           208 ≠ 256

B.) 6² +  7² =  8²

   36 + 49 = 64

           85 ≠ 64

C.) 5² +  12² =   13²

    25 + 144 = 169

            169 = 169

The numbers 5, 12, and 13 could represent the lengths of the sides of a right triangle.

D.) 16² +    32² =    36²

   256 + 1024 = 1296

              1280 ≠ 1296

Calculate the pay for the following day of a
tino4ka555 [31]

Answer:

Step-by-step explanation:

In the morning he works four hours and 15 minutes and in the afternoon he works four hours and 15 minutes for a total of eight hours and 30 minutes. 30 minutes is 1/2 of an hour so he works for a total of 8 1/2 hours. Multiply this by his hourly rate which is $15 and this gives you $127.50

15 x 8.5 = 127.5
