Answer:
Isosceles triangle
Step-by-step explanation:
If the measure of two sides or two angles of a triangle are equal, then it is isosceles triangle.
Answer:
y= -3x-1
Get the slope from the equation by getting y by its self then dividing everything by -1, which gives you y=-3x-12. You the -3 as your slope when doing the point-slope form.
Answer:
180°
Step-by-step explanation:
Answer:
186 cm²
Step-by-step explanation:
<em>*First we can move the shape around a bit to make it simpler to solve. If we take the triangle from the left side and move it over to the right, it connects with the other piece to create a rectangle. This leave two rectangles total which is much easier to solve.</em>
<em>*To find the length of the right rectangle, you take the 22 cm at the bottom and subtract the 12 cm (which is being used as the length for the left rectangle). This will give you a length of 10 cm long.</em>
<u>Left rectangle:</u>
A = lh
A = 12 (8)
A = 96 cm²
<u>Right rectangle:</u>
A = lh
A = 10 (9)
A = 90 cm²
<u>Total:</u>
A = 90 + 96
A = 186 cm²
