Answer:
E = 102
Step-by-step explanation:
1) Write down what angles you already know
A = 38 (given)
D = 26 (given)
B = 90
2) Work out the angles in the triangle
A triangle has 180 degrees so...
- 38 + 90 = 128
- 180 - 128 = 52
3) Work out the angles on the straight line
From the previous calculation we know that C = 62 (as it was the remaining angle)
Angles on a straight line should add up to 180 and we are given that D = 26...
- 52+26 = 78
- 180 - 78 = 102
- E = 102
Hope this helps, have a great day!
Answer:
Angle E = 102°
Step-by-step explanation:
In the figure, angle A measures 38
degrees and angle D measures 26
degrees. What is the measurement of angle E?
- the sum of the internal angles of a triangle is 180°, we know that the angle B measures 90° and the angle A measures 38°, we subtract the angles A and B from 180° and we find the angle C
180 - 38 - 90 = 52° (Angle C)
- now that we have angle C and angle D we can find angle E. they are all on a straight line, so the sum is 180°, from 180° we subtract angle C and D and we have angle E
180 - 52 - 26 = 102 (Angle E)
---------------------------
check
D + C + E = 180
26 + 52 + 102 = 180
180 = 180
the answer is good
- the other answer is wrong
