Given:
ABCD is a quadrilateral inscribed in a circle.
m∠A = (2x + 38)°, m∠B = 3x° and m∠D = (x + 20)°
To find:
Measure of angle C
Solution:
<em>In cylic quadrilateral, sum of the measures of opposite angles are 180°.</em>
m∠B + m∠D = 180°
3x° + x° + 20° = 180°
4x° + 20° = 180°
Subtract 20° from both sides.
4x° + 20° - 20° = 180° - 20°
4x° = 160°
Divide by 4 on both sides, we get
x° = 40°
<em>In cylic quadrilateral, sum of the measures of opposite angles are 180°.</em>
m∠A + m∠C = 180°
2x° + 38° + m∠C = 180°
2(40)° + 38° + m∠C = 180°
80° + 38° + m∠C = 180°
118° + m∠C = 180°
Subtract 118° from both sides, we get
m∠C = 62°
The measure of angle C is 62°.
Answer:
p= -14
Step-by-step explanation:
3/7 p + 12 = 6
sove using inverse operations
3/7 p +12 = 6
-12 -12
3/7 p = -6
*7 *7
3p = -42
/3 /3
p = -14
Answer:
b. $146,000
Step-by-step explanation:
1 usd = 146 jmd
1000 = ___ jmd
We multiply 1000 and 146:
1000($146) = $146,000
