Answer:
60°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 ( pentagon ), thus
sum = 180° × 3 = 540°
let x be the size of the equal angles
Sum the interior angles and equate to 540
(3 × 140 ) + 2x = 540
420 + 2x = 540 ( subtract 240 from both sides )
2x = 120 ( divide both sides by 2 )
x = 60
Thus the size of 1 of the 2 equal angles = 60°
Answer:
Greater :D
hope this helped (i may not be right)
Step-by-step explanation:
ANSWERx = 5/4
EXPLANATION Note that
so
Note that on the left-hand side, we can use exponent properties for multiplying two powers of the same base together:
We can now equate the exponents because both sides of the equation are of the same base with no other terms.
The answer is x = 5/4. We can confirm this by using this value in the original equation to get a true statement.
Answer:
III
Step-by-step explanation:
the answer would be the third one because if you divided the three numbers by 3 then they will be 3,5,4 which is a type of right angled triangle...you can also check it with pythagoras theorm.
It is 100 degrees because angles z and w need to equal 180 and a triangles angles always answer 180 degrees with angle y being 20 and an 80 degree angle making angle z 80 degrees making angle w 100 degrees.
