9514 1404 393
Answer:
47°, 86°
Step-by-step explanation:
The other base angle is congruent, so measures 47°.
The third angle brings the total angle measure to 180°, so has measure ...
180° -2(47°) = 86°
The other two angles have measures 47° and 86°.

Answer:
- DE ≈ 9.49, EF ≈ 8.06, FD ≈ 14.87
- obtuse scalene triangle
Step-by-step explanation:
For finding side lengths, it is convenient to work with the differences of the coordinates.
DE = E(-1, -3) -D(8, -6) = (-9, 3)
EF = F(-2, 5) -E(-1, -3) = (-1, 8)
FD = D(8, -6) -F(-2, 5) = (10, -11)
Then the lengths are ...
DE = √((-9)² +3²) = √90 = 3√10 ≈ 9.49
EF = √((-1)² +8²) = √65 ≈ 8.06
FD = √(10² +(-11)²) = √221 ≈ 14.87
The lengths are all different and the largest angle is obviously more than 90°, so the triangle is an obtuse scalene triangle.
57 because 5(6)+3(7)+6 is 30+21+6=57
Answer:
6
Step-by-step explanation:
Maybe you want a suitable common denominator for 2/3 and 1/6. If so, you can observe that 3 is a factor of 6, so 6 is a suitable common denominator.
2/3 = (2/3)·(2/2) = (2·2)/(3·2) = 4/6
The equivalents, 4/6 and 1/6, share a common denominator of 6.
The answer would be 3.
In order to find this you must place the values in where you see the letters. So start with the letters and plug in.
mx - y
Since m = 1, put that in.
(1)x - y
Since x = 5, put that in
(1)(5) - y
Since y = 2, put that in
(1)(5) - (2)
Now follow the order of operations and solve
(1)(5) - 2
5 - 2
3
