HL postulate.

Step-by-step explanation:

In the given triangles,

  • AC = BC ( given )

  • Angle ADC = Angle BDC ( 90° )

  • DC = DC ( common side )

hence, the triangles are congruent by HL postulate .

Answer:

4/9

Step-by-step explanation:

Find the GCD (or HCF) of numerator and denominator

GCD of 16 and 36 is 4

Divide both the numerator and denominator by the GCD

16 ÷ 4

36 ÷ 4

Reduced fraction:  

4

9

Therefore, 16/36 simplified to lowest terms is 4/9.

What is the equation of a line with a x-intercept of −2 and a y-intercept of 10?
IceJOKER [234]

Hey there! :)

Answer:

y = 5x + 10

Step-by-step explanation:

From the information given, we can derive the points (-2, 0) and (0, 10). Find the slope using the slope formula:

m = \frac{\text{rise}}{\text{run}} = \frac{y_2 - y_1}{x_2 - x_1}

Plug in the points:

m= \frac{10 - 0}{0 - (-2)}

Simplify:

m= \frac{10}{2}

m = 5.

The equation in slope-intercept form is y = mx + b. We were already given the b value, or y-intercept as y = 10. Therefore:

y = 5x + 10 is the equation written in slope-intercept form.
