Answer: isosceles
Step-by-step explanation:
By the alternate interior angles theorem, ![\angle CAB=50^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20CAB%3D50%5E%7B%5Ccirc%7D)
Since angles in a triangle add to 180 degrees, ![\angle ACB=180^{\circ}-80^{\circ}-50^{\circ}=50^{\circ}](https://tex.z-dn.net/?f=%5Cangle%20ACB%3D180%5E%7B%5Ccirc%7D-80%5E%7B%5Ccirc%7D-50%5E%7B%5Ccirc%7D%3D50%5E%7B%5Ccirc%7D)
Since sides opposite equal angles in a triangle are equal,
.
So, triangle ABC is <u>isosceles</u>
Answer:
(1,-7)
Step-by-step explanation:
1) (5,-4). 4 units to the left will be (1,-4)
2) (1,-4). 3 units down will be (1,-7)
A line will cross the y-axis when x=0, so we plug in zero to get the y-value.
y=3(0)-2 = -2
The line crosses the y-axis at the point
G = (0,-2).
Okay, I got no clue what’s going on but okay
Answer:
36 1/4 in³
Step-by-step explanation:
v = 3 5/8 * 2 1/2 * 4
Convert to improper fractions
v = 29/8 * 5/2 * 4/1
Cancel
v = 29/2 * 5/2 * 1/1
Multiply
v = 145/4
Reduce
v = 36 1/4 in³
