Explanation 1:
Jennifer knows that at least one of Franklin's measures of the angles of the triangle is incorrect because the sum of the inner angles of a triangle is equal to 180°.
When you add the shown measures you get:
- 37° + 97° + 134° = 268° ≠ 180°, which makes this an impossible triangle.
Explanation 2:
Jennifer also can know that either the measure 97° or 134° (or even both) is incorrect.
This is so because the addition of those two measures is
Since 231° > 180° those measures cannot be correct because the sum of two angles of an triangle has to be less than 180°, given that when they are summed to the other angle the sum has to be 180°.
The surface area of a sphere is π x 4 x radius²
so let the radius be r
π x 4 x r² = 2122.64
r = 13 inches
The answer is D, the alternate exterior angles theorem.
Alternate, because the two angles are on opposite sides of line t.
Exterior, because both angles are outside of the parallel lines.
Therefore, alternate exterior angles theorem.
There are no parentheses or exponents, so the Order of Operations tells you to start by performing division and multiplication left to right.
7-3+4÷2×6
= 7-3+2×6
= 7-3+12
After you have done that, you perform addition and subtraction left to right.
= 4 +12
= 16
