Mathematics
1 answer:
DENIUS [597]3 years ago
7 0

Answer:

m<K = 90°

m<L = 39°

m<M = 51°

Step-by-step explanation:

This is z right triangle and thd angle of K is 90°

Since the sum of interior angles in a triangle is equal to 180° The sum of other two angles will be 90°

3x + 21 + 2x + 19 = 90 add like terms

5x + 40 = 90

5x = 50

x = 10

m<L is 2x + 19 ➡ 2×10 + 19 = 39°

m<M is 3x + 21 ➡ 3×10 + 21 = 51°

The triangle will be dilated by a scale factor of 1.5. (a) Calculate the length of each side of the dilated image. (b) Draw the
VLD [36.1K]
To find the new sides take the original sides and multiply it by the scale factor

12 * 1.5 = 18
10 * 1.5 = 15
14 * 1.5 = 21

So the new sides are 18, 15, 21.  And they correspond to the 12, 10, and 14 respectively

Paul, Colin and Brian are waiters.
Kisachek [45]

Add the ratios together: 2 + 3 +4 = 9

Divide the total tips by 9:

77.40 / 9 = 8.60

Multiply each portion of the ratio by 8.60:

2 x 8.60 = 17.20

3 x 8.60 = 25.80

4 x 8.60  = 34.40

The ratios are in order of the people:

Paul got 17.20

Colin got 25.80

Brian got 34.40

Brian got 34.40 - 17.20 = 17.20 more than Paul

What the equation of this graph?? I need help
yuradex [85]
X = 3

and

formula -

(y-y1)/(x-x1) = (y2-y1)/(x2-x1)

(x1,y1) = (4,1)
(x2,y2) =( 5,3)

(y-1)/(x-4) = (3-1)/(5-4)

y-1/x-4 = 2/1

y-1 = 2x - 8

y = 2x - 7

the solution will be x= 3 and y = -1

How to classify a triangle by side and angle ?
s2008m [1.1K]

By angle:

We can classify a triangle 4 different ways when we're judging it by it's angle(s).

Acute: A triangle where all angles are less than 90 degrees.

Obtuse: A triangle where one angle is greater than 90 degrees.

Right: A triangle where one of the angles is exactly 90 degrees.

Equiangular: A triangle where all angles are the same (60 degrees.)


We can also classify a triangle by its sides:

Equilateral: (technically the same as an equiangular triangle, in order to have 3 equal sides you must have 3 equal angles as well.)

Isosceles: Two sides are the same length, where one is not.

Scalene: All three sides are different lengths.


I hope this helps!
