Because the quadrilateral is inscribed in a circle, the opposite angles will add up to 180°. Because of this, we can set up this equation:
2x + 9 + 3x + 1 = 180
Now, we can solve for x. First, we should combine like terms. Now, the equation is:
5x + 10 = 180.
Now, we need to get x on its own side. We do this by subtracting 10 from both sides.
5x = 170.
Finally, we can divide both sides by 5 to figure out what x is.
x = 34
In order to finish the problem, we just need to substitute this back into the expression for a.
2*34 + 9 = 68 + 9 = 77, so angle a is 77°.
The width to your question is 26.67 i got this by dividing 320 by 12 which = 26.67, hope this helps.
Its the first choice. d(6) = 176.4 and d(3) = 132.3 A difference of 44.1 m
Answer:
Here
Step-by-step explanation:
7 = 4x + 7
Cancel out the 7's on each side by adding negative 7 to both sides...
0 = 4x
Now find how much for x alone
4x = 0
divide both sides by 4
x = 0
X = 0
7 = 0 + 7
7 = 7
Answer:
Side AC is congruent to side DF
Step-by-step explanation:
We are given that
Side AB=5 cm
BC=6 cm
Side DE=5 cm
Side EF= 6cm
We have to find an additional information would need to prove that by SSS.
When two triangles are congruent by SSS it means three sides of one triangle are congruent to corresponding sides of other triangle.
We have in triangle ABC and triangle DEF
Then ,DEF
Reason: SSS postulates
Answer: Side AC is congruent to side DF
