Answer:
Step-by-step explanation:
23). By applying triangle sum theorem in the given triangle,
(x + 83)° + (x + 48)° + 65° = 180°
2x + 196 = 180
2x = -16
x = -8
Measure of angle A = x + 48
= -8 + 48
= 40°
Therefore, Option A is the answer.
24). By triangle sum theorem,
(3x + 14)° + 90° + (4 + 3x)° = 180°
6x + 108 = 180
6x = 72
x = 12
Measure of angle A = (4 + 3x)
= 4 + 3(12)
= 40°
Therefore, Option A is the answer.
Answer:
x = 101°
y = 46°
Step-by-step explanation:
The question tells us that ΔSTU is similar to ΔSVW. This means that the corresponding angles in each triangle are the same. We can write that like this:
∠UST = ∠WSV
∠SUT = ∠W
∠STU = ∠V
We can then fill in the angles we know into these statements.
33° = 33°
101° = x
y = 46°
Now we know the values of x and y.
x = 101°
y = 46°

Answer:
1
Step-by-step explanation:
The average rate of change is the gradient _
Gradient = Rise / Run = (y2 - y1) / (x2 - x1)
From the table ;
x2 = 4 ; x1 = - 1 ; y2 = 5 ; y1 = 0
Gradient = (y2 - y1) / (x2 - x1) = (5-0) / (4 - - 1) = 5/5 = 1
