Answer:
A. 47 degrees
Step-by-step explanation:
If both sides are equivalent in length, that means that the two remaining angles are also the same. Triangles have an interior angle sum of 180 degrees, so subtract the 86 of the angle known, and divide the remaining degrees by two to find each angle.
Answer:
Then the desired equation is y = -2x - 6.
Step-by-step explanation:
As we move from point (-3, 0) to point (0, -6), x increases by 3 and y decreases by 6. Thus, the slope of the line segment connecting these two points is m = rise / run = -6/3 = -2.
Now use the slope-intercept equation of a straight line to determine the y-intercept of this line:
y = mx + b becomes 0 = -2(-3) + b, so that b = -6.
Then the desired equation is y = -2x - 6.
Check: Does (0, -6) satisfy y = -2x - 6? Is -6 = -2(0) - 6 true? YES
Answer:
both are wrong
Step-by-step explanation:
raj's mistake: he did not multiply -2 by -5a/4
antonia's mistake: she went from -4a/4 to a which is wrong because -4/4 is -1.
For the 1st one RSV = TSU (Vertical angles are congruent)
9x - 28 = 6x + 2
3x = 30
x = 10
RSV = 62
The 2nd one
Alternate exterior angles are congruent
Thus
10x + 5 = 125
10x = 120
x = 12
The 3rd one
When triangles are similar their sides are promotional and their angles are congruent
thus
A and D
The 4th one
Find Angle A
Angle A + 3Angle A + 76 = 180
4 Angle A = 104
Angle A = 26
