I think this is the answer
The answer is choice C
Plane D(choice C) because choice a and b are not lines(one letter cannot be a line and PBC and not connected). It's not d because e isn't a point
Point S makes the two connected angles the same. They both have right angles.
And one side of each is congruent.
This means you know 2 angles are the same and one side is the same.
You would use ASA (Angle, Side, Angle)
Question:
Find the gradient of the line passing through (6,8) and (4,10).
Answer:
-1 is the right answer.
Step-by-step explanation:
Slope of the line = The gradient of the line
Gradient of the line is known as change in the value of y-axis by change in the value of x-axis
Gradient = ∆y\∆x
Answer:
m∠A = 65°
Step-by-step explanation:
Because ∠CBD is congruent to ∠DBE, we can set the degree values equal to each other.
So
CBD has x + 10, DBE has 60. So:
x + 10 = 60
Subtract 10 from both sides.
x = 50
Check:
50 + 10 = 60
60 = 60
m∠A = (x + 5)° = (60 + 5)° = 65°
