Answer: AB 90 IB 150 IC 135 AC 90
Step-by-step explanation:
All triangles have to equal 180, if B is 60 and I is 90, 60+90=150, 180-150=30 then A=30 if a equals 30 than 60+30=90 A+B=AB (same with the others.)
Answer:
16 and 38
Step-by-step explanation:
Given 2 sides of a triangle then the third side x
difference of 2 sides < x < sum of 2 sides , that is
27 - 11 < x < 27 + 11
16 < x < 38
Vertical angles are congruent.
2 is 153
There are many for this ,but one sample is: 2 divided by 2is 4 X 3 which is 12.
Follow PEMDAS (parenthesis- exponents (& roots) - multiplication - division - addition - subtraction)
18/3 = 6
22 - 10 = 12
12 + 6 = 18
18 is your answer
hope this helps
