- Answer:
<em>OB = 3 cm</em>
- Step-by-step explanation:
<em>AO = radius = 5 cm</em>
<em>AB = 8cm/2 = 4 cm</em>
<em>Pythagora</em>
<em>OB² = AO² - AB²</em>
<em>= (5cm)² - (4cm)²</em>
<em>= 25cm² - 16cm²</em>
<em>= 9 cm²</em>
<em>OB = √9cm²</em>
<em>= 3 cm</em>
If we know that line is equal to line
, then this means that ∠
has to be equal to ∠
in order to form a closed triangle. All angle measures of a triangle add up to
°, so use the equation:
.
70 + x = 180
Subtract 70 from both sides to isolate x:
180 - 70 = 110
110 = x
