Answer:
<C =10°
Step-by-step explanation:
The sum of angles in a triangle is 180°. Hence,
<C+<D+<E =180
Given
<C =x-4
<D = 11x-11
<E = x+13
Substitute
x-4+11x-11+x+13 = 180
13x-2 = 180
13x =180+2
13x = 182
x = 182/13
x = 14
Get <C
Since <C = x-4
<C = 14-4
<C =10°
Answer:
y = 4x - 5
Step-by-step explanation:
for slope intercept form
y = mx + c
where m is the slop so
M = 4
point = (1, -1)
a point on the line must satisfy the equation so replacing y and x by -1 and 1 respectively to get to c.
-1 = 4 × 1 + c
-1 - 4 = c
-5 = c
placing these values in y = mx + c
y = 4x - 5
The union of the two sets is the combining of the two sets, so the correct answer is A. {4, 8, 10, 12, 14}.
Hope this helps =)
I think it’s the second one sorry if i’m wrong
