Answer:
Congruent by ASA
Step-by-step explanation:
2 pairs of corresponding angles are given equal.
Also side DC is common to both triangles.
So the 2 triangles are congruent by ASA
Answer:
66
Step-by-step explanation:
We know <em>x </em>= -4. To solve, we just need to plug in -4 for <em>x</em>.
6 (-4 + 15) =
6 (11) =
66
Answer:
Step-by-step explanation:
The answer is 1.3
Answer:
120 is 60% of 200
Step-by-step explanation:
Step 1 = 120 = 60% × Y
Step 2 = 120 = 60/100 × Y
Step 3 = Y = 120 × 100/60
Step 4 = Y = 120 × 100 ÷ 60
Step 5 = Y = 200
Answer:
(c)
will be perpendicular to the line y = 3x+2
Step-by-step explanation:
We have given the the equation of line as y = 3x+2
We know the equation of line as y = mx+c , here m is slope and c is intercept
On comparing with standard equation of line m = 3
We know that slope of perpendicular line is ![=\frac{-1}{m}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-1%7D%7Bm%7D)
So the slope of the line which is perpendicular to y = 3x+2 will be ![=\frac{-1}{3}](https://tex.z-dn.net/?f=%3D%5Cfrac%7B-1%7D%7B3%7D)
Now (a) Line is given as
its slope is
so it will be not perpendicular
(b) Line is given as
its slope is
so it will be not perpendicular
(c) Line is given as
its slope is
so it will be perpendicular to the line y = 3x+2
(d) Line is given as
its slope is 3 so it will not perpendicular to the line y = 3x+2
