Answer:
16
Step-by-step explanation:
Answer:
In words, if the hypotenuse and a leg of one right triangle are congruent to the hypotenuse and a leg of a second right triangle, then the triangles are congruent. If in triangles ABC and DEF, angle A = angle D = right angle, AB = DE (leg), and BC = EF (hypotenuse), then triangle ABC is congruent to triangle DEF.
Slope-intercept form:
y = mx + b
"m" is the slope, "b" is the y-intercept (the y value when x = 0) or (0,y)
To find "m", you can use the slope formula and plug in the two points:
(2,3) = (x₁ , y₁)
(0,9) = (x₂ , y₂)



m = -3
y = -3x + b
To find "b", you can plug in one of the points into the equation (however they already gave you the y-intercept (0,9) or 9)
(2,3)
y = -3x + b
3 = -3(2) + b
3 = -6 + b
9 = b
y = -3x + 9
Set up a proportion:
3cm/2m = x/1m
Cross-multiply:
2x=3
Divide by 2:
x=1.5 cm
The first one because there is no expressions in this problem except for C<span />
