Answer:

75.775

Step-by-step explanation:

the sum of all angles in a triangle is ALWAYS 180°.

and by using the word "congruent" : for angles that only means they are equally large so,

180 = P + Q + R = 2×P + 28.45

(because P = Q)

2×P = 151.55

P = Q = 151.55 / 2 = 75.775°

Step-by-step explanation:

the sum of all angles in a triangle is ALWAYS 180°.

and by using the word "congruent" : for angles that only means they are equally large.

we know the third angle.

so,

180 = P + Q + R = 2×P + 28.45

(because P = Q)

2×P = 151.55

P = Q = 151.55 / 2 = 75.775°

Write the equation of a line that has a m= -5 and passes through the point (-1,4)
svetoff [14.1K]

Answer:

We have a slope and a point, this way, we do not need to find the slope using two points. We can find the line using the Slope Form to turn it into Slope-Intercept Form, also known as "y = mx + b". We can use the Slope Form which is "y - y1 = m(x - x1)". A coordinate is "(x,y)", so that means, "(-1,4)" means that x = -1 and y = 4. We can substitute y1 for 4 and x1 for -1, and m for -5 since m is the slope. Plugging that information into the Slope Form Formula we get "y - 4 = -5(x - (-1))". We know that a negative with a negative turn positive, so we can use this information to change the formula to "y - 4 = -5(x + 1)". Now we distribute and simplify, these steps are shown below.

y - 4 = -5(x + 1)

y - 4 = -5x -5

y - 4 + 4 = -5x - 5 + 4

y = -5x - 1

Now that we have simplified it, we can see that the slope is -5 and the -1 is the y-intercept. To check this is a linear equation is to graph it, or substitute three x-coordinate or y-coordinates and draw a line. In conclusion, the equations is y = -5x - 1.

What value for y makes this equation true?
3241004551 [841]
The answer is D. 48.

(3 x 40) + (3 x 8)
120 + 24
144

3 x Y = 144

Divide 144 by 3

144 / 3 = 48.
So the answer is 48.

Hope this helps!!

Help me on question 24 please and explain it thanks

You know that the sum of the interior angles in a triangle is 180
we will add all the angles,
(x+8)+(2x-8)+(3x-12)=180
x+8+2x-8+3x-12=180    8 and -8 cancel out 
6x-12=180
6x=180+12
6x=192
x=192/6=32
x=32
