Answer:
No
Step-by-step explanation:
A right triangle's sides add up to 180 but adding 32, 60, and 68 only gives you 160. So, no. That triangle is not a right triangle.
I hope I helped ^^
Answer:
1. x= 20/3 or 6.6666 repeating
2. x=3
3. a=39
Step-by-step explanation:
1. subtract 25 by 5 to get 20, then divide 20 by 3 to get x
2. divide 7 by 21 to get x
3. add 8 to 31 to get a equals 39
You have to be able to know the appropriate properties or postulates to apply on the angles or segments to simplify them. An example would be the Angle Addition Postulate. This postulates states that the sum of the individual measures of the interior angles is equal to the measure of the included angle. There are still a lot more properties to choose from depending on the situation.
Answer:
True
Step-by-step explanation:
The absolute value of -12 is 12 so both numbers are equal.
have a nice day :)
Answer:
Since EF bisects ∠DEF, we know that EF splits ∠DEF in 2 halves from the word 'bisects', which can be written as 'bi- sects' , where bi means 2 and sects means sections
Hence, ∠DEG = ∠GEF --------------(1)
We are given the measure of these angles:
∠DEG = 3x - 4
∠GEF = x + 13
Now, replacing the values in (1):
3x - 4 = x + 13
2x = 17
x = 17/2
Now, finding the measure of ∠DEF:
∠DEF = ∠DEG + ∠GEF
∠DEF = 3x - 4 + x + 13
∠DEF = (51 / 2) - 4 + (17/2) + 13 (x = 17/2)
∠DEF = 34 - 4 + 13
∠DEF = 43°
