Answer 
Step-by-step explanation:
Use order of operations and evaluate the exponent first




Answer:
True.
Step-by-step explanation:
These angles are congruent because lines DE and BC are parallel.
Answer:
16
Step-by-step explanation:
Since 2+2 is in parenthesis you do that first. So now you have 8/2(4). 8/2= 4. 4*4 = 16
HD = 10.5
Step-by-step explanation:
Given BH = 3, GH = 2, BF = 10
Step 1: To find HF:
HF = BF – BH
HF = 10 – 3
HF = 7
Step 2: To find HD:
We know that if two chords intersects inside a circle, the product of the lengths of the segments of one chord equals the product of the lengths of the segments of the other chord.
⇒ GH × HD = BH × HF
⇒ 2 × HD = 3 × 7
⇒ HD = 10.5
Hence, the value of HD = 10.5.
