43) ang 1 = ang 2
5x = 9(x-4)
5x = 9x - 36
4x = 36
x = 9. so ang 1 + ang 2 = 90°

44) ang 1 +ang 2 + ang 3 = 180
60 + 7x+1 + 9x+7 = 180
16x = 112
x = 7
so angle 2 is 7*7+1= 50°
angle 3 is 9*7+7= 70°

45) let ang 2=x, then ang 1 is 3x
then 3x+x=96
4x = 96
x=24
angle 2 is 24° and angle 1 is 72°

Trigonometry... hellpp plzzz​
rjkz [21]

Answer:

17.1 degrees

Step-by-step explanation:

This is a tangent question because angle XYZ is adjacent to 13 and opposite of 4. This means that we will have to use opposite/adjacent. This is very simple if you know the formula. Just plug those numbers in to get 4/13 = 0.3076923076923077. However, now we need to find it in degrees. If you have an inverse calculator near you, you would plug it in to get about 17.10, which rounds to 17.1.

Find the value of B - A if the graph of Ax + By = 3 passes through the point (-7,2), and is parallel to the graph of x + 3y = -5
Gnoma [55]

The required simplified value of B - A = -6.

<h3>What is simplification?</h3>

The process in mathematics to operate and interpret the function to make the function simple or more understandable is called simplifying and the process is called simplification.

Since, line Ax + By = 3 and x + 3y = -5 are parallel than slope of both the line will be same,
m = -1/3 = -A/B
From above
A = B/3  - - - - -(1)


Now line Ax + By = 3 passed through the point (-7, 2). So,
-7A + 2B = 3
from equation 1
-7B/3 + 2B = 3
-B/3 = 3
B = -9
Now put B in equation 1
A = -9 / 3
A = -3

Here,
B - A = -9 + 3 = -6

Thus, the required simplified value of B - A = -6.

In three to five sentences, explain the importance of sentence structures in good writing.
jenyasd209 [6]

Answer:

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

Step-by-step explanation:

Sentence structure is very essential to convey the idea of the writer 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.
