Answer:

55 degrees

Step-by-step explanation:

Add the expressions up and set up an equation.

( 2 x − 29 ) + ( x + 23 ) = 90 Simplify and solve for x.

3 x − 6 = 90 3 x = 96 x = 32 Find angle B.

x + 23 = 32 + 23 = 55

Hope this helps, have a nice day/night! :D

Answer:

m∠B = 61°

Step-by-step explanation:

Complementary means two angles that add up to the sum of 90°.

Since we are given m∠A = 29°, subtract 29° from 90°.

90 - 29 = 61

m∠B = 61°

Use the figure to the right to find the value of PT. T is the midpoint of PQ.
Ghella [55]

Answer:

<em>PT=30 units</em>

Step-by-step explanation:

Given that:

Line PQ which has a mid point at T.

PT = 3x + 9 and

TQ = 5x -5

To find:

PT = ? in simplified terms.

Solution:

First of all, let us recall that mid point on a line segment is a point that divides the line in two equal parts.

In other words:

If a point B is the mid point of line segment AC, then AB = BC.

Here, the point T is the midpoint of PQ.

i.e. PT = TQ

3x+9=5x-5\\\Rightarrow 3x-5x=-5-9\\\Rightarrow -2x=-14\\\Rightarrow x=7

Putting value of x in PT above:

PT = 3x+9 = 3 \times 7 +9 \\\Rightarrow \bold{PT=30\ units}
