Question 1:
It is given that BC = EC and AC = DC. According to the definition of vertical angles, ∠BCA = ∠DCE. Thus, the two triangles are congruent by SAS. According to CPCTC, BA must be congruent to ED.
Edit this paragraph to make it more "yours"
Question 2:
A and E are base angles.
B and D are legs.
F is the base.
C is the vertex angle.
Have an awesome day! :)
I hope this helps you
3x^2-x-2
3x +2
x -1
(3x+2)(x-1)
Than always means you have to flip the expression
200 less than half a number
-200 <-> 1/2 x
x×1/2-200 or x÷2-200
A full circle is 360 degrees, so subtract your other values from that, making 178. The opposite angle is a right triangle, which is 90 degrees. So that means angle ED is 88 degrees.
Answer:b -2
Step-by-step explanation:
8t + 5 = 6t + 1 subtract 1 from both sides
8t + 4 = 6t subtract 8t from both sides
4 = -2t divide -2 from both sides
-2 = t
Have a nice day :)
