We can use the fact that a cyclic quadrilateral (i.e. a quadrilateral inscribed in a circle) has the opposite angles supplementary, therefore
2x+(2x+4) = 180
Solving for x:
4x+4=180
4x=180-4=176
x=176/4=44 °
=>
angle O = 2x = 88 °
angle Q=180-O=180-88 = 92 °
Similarly,
(3y+8)+y= 180
=> y=43 °
=>
P=y=43 °
R=180-43=137 °
Answer:
The inverse is
Step-by-step explanation:
The options are not provided.
However, I will show you how to find the inverse of
We interchange x and y to get,
We solve for y,
Use the fact that the sum of interior angles of a triangle is equal to 180°.
Hence, the second and the third angles of the given triangle are 180-115/2= 65/2<span>
(32 degrees and 30 minutes).</span>
Answer:
30
Step-by-step explanation:
Given the radical values;
√1000
= √100 * √10
= 10√10
= 10 (3.1623)
= 31.623
Converting to nearest 10,
= 30
Hence the value to the nearest 10 is 30
