Answer:
They are similar. Triangle abc is similar to triangle edc.
Step-by-step explanation:
To prove that triangles are similar, you must show that the 3 angles in one triangle are equal to the 3 angles in the other triangle. We know that they both have a 50 degree angle. We can also see that they both have a right angle. That means that the 3rd angle must also equal 40 (180-90-50). So by AAA the two triangles are congruent.
Triangle ABC is similar to triangle EDC.
Answer:
See below.
Step-by-step explanation:
2−4÷2+23 =
= 2 - 2 + 23
= 0 + 23
= 23
This is the answer of the problem you posted, where 23 is the number twenty-three. 23 is not an answer choice, so perhaps 23 is not the number twenty-three, but rather 2 to the 3rd power, 2^3.
2−4÷2+2^3 =
= 2 - 2 + 8
= 0 + 8
= 8
8 is one of the choices.
