In triangle ABC, it is given that angle A is 59 degrees and angle B is 53 degrees. The altitude from B to line AC is extended un

dsp73

Answer:

∠AKB = 22°

Step-by-step explanation:

Call the point of intersection of BK and AC point P. Then line BK is a transversal to parallel lines AK and BC. Alternate interior angles AKB and PBC will be congruent.

We know that angle PCB is 68°, the difference between 180° and the sum of the two given angles in ΔABC:

∠PCB = 180° -∠PAB -∠ABC = 180° -59° -53° = 68°

Since PB is an altitude, ∠CPB is a right angle. Then ∠PBC is the complement of ∠PCB, so is ...

∠PBC = 90° -68° = 22°

As we said, this is congruent to ∠AKB, so ...

∠AKB = 22°

Look at the figure. Find the value of CG.

vladimir2022 [97]

Answer:

x = 6

Step-by-step explanation:

As before, ray BG is an angle bisector. This makes CG and AG equal.

4x - 16 = 2x - 4

2x - 16 = -4

2x = 12

x = 6

To check:

4(6) - 16 = 2(6) - 4

24 - 16 = 12 - 4

8 = 8

Determine the x-intercept for 3x + 2y = 14. A) (7, 0) B) (0, 7) C) ( 14 3 , 0) D) (0, 14 3 )

Anettt [7]

Answer:

$\large\boxed{C.\ \left(\dfrac{14}{3},\ 0\right)}$

Step-by-step explanation:

$\text{The x-intercept is for y = 0.}\\\\\text{Put y= 0 to the equation}\ 3x + 3y = 14:\\\\3x + 3(0) = 14\\\\3x + 0 = 14\\\\3x = 14\qquad\text{divide both sides by 3}\\\\x =\dfrac{14}{3}$
