Answer:
The answer is the option C

Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal angles
The two equal angles are called the base angles, and the third angle is called the vertex angle
In this problem we have the isosceles triangle TIC
∠I=
-----> vertex angle
∠T=∠C -----> base angles
Remember that the sum of the internal angles of a triangle is equal to 
so
∠I+∠T+∠C=
∠I+2∠T=
Substitute
+2∠T=
Solve for angle T
2∠T=
∠T=
∠T=
Answer:
B
Step-by-step explanation:
36/12=3 feet
Bell:
1 hour = 10 miles
4.5 hours = 10 x 4.5 = 45 miles.
Kristin:
1 hour = 14 miles
4.5 hours = 14 x 4.5 = 63 miles
Difference in distance = 63 - 45 = 18 miles.
Answer: They will be 18 miles apart.
If you substitute the values x = 0 and y = −5 into the second equation, you get a false statement: 2(−5) − 10 = 2(0). To solve this system, try rewriting the first equation as x = 2y − 8. Then substitute 2y − 8 in for x in the second equation, and solve for y. The correct answer is x = −2, y = 3.
Equilateral triangle<span> is a </span>triangle<span> in which all three sides are equal
</span>also 3 angles are equal and each angle = 60 degrees
so
2x - 4 = 60
2x = 64
x = 32
