Answer:
Sari didnt use correct factors for 40 in the equation
Given that ∠CEA is a right angle which has been bisected by BE, then:
∠CEB=∠BEA
thus each angle will be complementary to each other, hence the size will be:
90/2=45°
hence the correct statement.
<span>m∠CEB = 45°</span>
Answer:
2 2/5
Step-by-step explanation:
Supplementary angles mean that two angles equal to 180°.
Let us assume the 2 angles are angle A and angle B.
Angle A is 4 times bigger than Angle B, the supplement.
Let Angle B be represented by x.
Angle A is 4x ; Angle B is x.
4x + x = 180°
5x = 180°
x = 180°/5
x = 36° This is the measure of angle B.
4x = 4(36°) = 144° This is the measure of angle A.
4x + x = 180°
144° + 36° = 180°
180° = 180°
