<u>Answer:</u>
A) Scalene E) Obtuse
<u>Detailed Explanation:</u>
A) Scalene
This triangle would be classified as scalene because none of the angles are equal.
____________________________________________________________
E) Obtuse
This triangle would be classified as an scalene triangle because one of the angles is larger than 90 degrees.
Step-by-step explanation:
5.
angle STQ is the supplementary angle (together they are 180° below line MQ) to 2x + 8.
above ST we have a group of 3 angles that combine to 180° :
2x + 8
90°
71 - x
so, to get x first :
2x + 8 + 90 + 71 - x = 180
x + 169 = 180
x = 11
so, the angle MTS =
2x + 8 = 2×11 + 8 = 22 + 8 = 30°.
6.
therefore, the angle STQ is
180 - angle MTS = 180 - 30 = 150°.
Answer:
-1
Step-by-step explanation:
Distribute
6x - 2 >= 4x - 6
2x >= -4
x >= -2
Answer:
Multiply row 1 by .
Step-by-step explanation:
The augmented matrix of the system of linear equation is described below:
Where , if we need to create , we need to multiply row 1 by , that is to say:
Hence, the correct answer is: Multiply row 1 by .
