Step-by-step explanation:

a = 4, R = 147, T = 33

Step-by-step explanation:

find a

a/(a + 7) = (16/3)/(44/3)

a/(a + 7) = 16/44

44a = 16a + 112

44a - 16a = 112

28a = 112

a = 112/28

a = 4

find R

2x + 5 = 3x - 9

5 + 9 = 3x - 2x

14 = x

m ∠R = 180° - (2x + 5)

= 180 - (2(14) + 5)

= 180 - (28 + 5)

= 180 - 33

= 147°

find T

m ∠T = 3x - 9

= 3(14) - 9

= 42 - 9

= 33°

Answer:

IJ = 12

Step-by-step explanation:

sum the parts of the ratios, 3 + 3 + 4 = 10 parts

Divide HK by 10 to find the value of one part of the ratio.

40 ÷ 10 = 4 ← value of 1 part of ratio , then

IJ = 3 parts = 3 × 4 = 12

To find b, start by subtracting 20 from both sides:

50 = -1/3b + 20

-20 -20

30 = -1/3b

Now isolate b by dividing both sides by -1/3:

30/(-1/3) = (-1/3b)/(-1/3)

-90 = b

b is 90!

Answer:

35miles/1 hr=21miles/x hr

= x hr* 35miles/1 hr= 21 miles

= x = 21/35 =0.6 hr

So, traveling at 35mph it will take 0.6 hours to travel 21 miles.

If you want time in mins then keep going:

=> 60 mins = 1 hour, 0.6 hours = x mins

60mins/1 hr = x mins/ 0.6 hr

0.6 * 60 mins = 36 mins.

:. It takes 0.6 hrs or 36 mins to drive 21 miles at a constant speed of 35mph

Answer:

see explanation

Step-by-step explanation:

The sum of the interior angles of a polygon is

sum = 180° (n - 2) ← n is the number of sides )

Here n = 5 , then

sum = 180° × 3 = 540°

Sum the given angles and equate to 540

2b - 90 + 90 + b + 45 + b + [tex]\frac{3}{2}[/tex] b = 540, collect like terms

4b + 1.5b  + 45 = 540 ( subtract 45 from both sides )

5.5b = 495 ( divide both sides by 5.5 )

b = 90

then

2b - 90 = 2(90) - 90 = 180 - 90 = 90

b + 45 = 90 + 45 = 135

[tex]\frac{3}{2}[/tex] b = 1.5b = 1.5 × 90 = 135

The angles from least to greatest are

90° , 90° , 90° , 135° and 135°

The required coordinate of the point K is (13, 8).

Given that,
The coordinates of point J are (-7, 2), and the midpoint of JK is at L (3, 5), the coordinates of point K is to be determined.

Coordinate, is represented as the values on x-axis and y-axis of the graph.

here,
The coordinate of the midpoint (x, y) is given as,
x = (x₁ + x₂)/2     ; y = (y₁ + y₂)/2
Substitute the value in the above equation,
3 = (-7 + x₂)/2     ; 5 = (2 + y₂)/2
x₂ = 13                ; y₂ = 8

Thus, the required coordinate of point K is (13, 8).
