Answer:
b and c
Step-by-step explanation:
so to answer this one we just plug in all of the answer choices to see which ones satisfy the inequality
for a we plug in b and get 5<8-3 or 5<5 which is not true so it cant be a
next we plug in 9, 5<9-3 or 5<6 so b is a correct answer
next we plug in 10, 5<10-3 or 5<7 which is correct so c is also a correct answer
hope this helps (:
Answer:
16 is the missing number
Step-by-step explanation:
Answer: B and D
Step-by-step explanation:
Angle B measures 30 degrees.
Step-by-step explanation:
Step 1:
If two angles are complementary, the sum of the two angles will equal 90°.
So if angles A and B are complementary, the sum of the angles A and B will equal 90°.
It is given that cos A = 0.5, we can determine the value of A by taking the cos inverse of the value 0.5.
Step 2:
If cos A = 0.5, A =
So angle A is 60°.
As A and B are complementary, angle A + angle B = 90°.
So 60° + angle B = 90°, angle B = 90° - 60° = 30°.
So angle B measures 30° while angle A measures 60°.
