If line xa is an altitude of triangle xyz, find xa

XA =  66 units.

Step-by-step explanation:

Given  : Triangle XYZ and  line XA is an altitude

To find : find XA.

Solution : We have given that Triangle XYZ and line XA is an altitude.

We can see from the triangle

Angle XAY = angle XAZ.

90° = 2x -72 .

On adding sides by 72

90 + 72 = 2x .

162 = 2x .

On dividing by 2 both sides.

81 = x .

Now,

Altitude XA = x -15

XA = 81 - 15 .

XA =  66 .

Therefore, XA =  66 units.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1

i believe that the slope of the line is -5
