Answer:
x = - 7
Step-by-step explanation:
Given
- 2(x + 5) = 4 ← distribute the parenthesis by - 2
- 2x - 10 = 4 ( add 10 to both sides )
- 2x = 14 ( divide both sides by - 2 )
x = - 7

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.
Answer:
x = 12.48
y = 13.22
Step-by-step explanation
Im not sure if its correct
10^2 + b^2 = 16^2
100 + b^2 = 256
b^2 = √156
b = 12.48
b= 12 ( If needed to round to the nearest whole number)
a^2 + 15^2 = 20^2
a^2 + 225 = 400
a^2 = √175
a = 13.22
a = 13 ( If needed to round to nearest whole number)
