Since BD bisects angle ABC, that means angle ABD and angle CBD are equal to each other. With that set up the equation to solve for x like this:
-4x+33 = 2x+81
-2x -2x
————————
-6x +33 = 81
-33 -33
————————
-6x = 48
————- (divide by -6)
-6
x = -8
Now substitute that to ABD
-4(-8) +33
32 +33
=65
here’s CBD
2(-8) + 81
-16 + 81
=65
Finally angle ABC will be double the amount of ABD or CBD so 65 times 2 is 130.
ANSWERS: (angles)
ABD and CBD: 65
ABC: 130
Answer:
X=98°
Step-by-step explanation:
53° + 45° = 98
98-180= 82
every triangle is always equal o 180°
so... 53°+ 45°+ 82° = 180
to find x you need to subtract 82 from 180 which is 98
<em>remember its important to find the inner degree before the outer.</em>
The answer you are looking for is -11/10 or - 1 1/10.
To find this answer you must first make the denominators the same. To do this, multiply 2/5 by 2/2 to get 4/10. Finally, subtract the two fractions, keeping in mind the denominators stay the same. -7/10 - 4/10 = -11/10 or - 1 1/10.
I hope this helps!
Answer:
23/20 or 1 and 3/20
Step-by-step explanation:
Make sure they have the same common denominator. For 5 and 4, 20 would be the Least Common Denominator.
so 2/5=8/20 and 3/4=15/20
Add 8+15 and you get 23 so 23/20 you can leave it so or switch it to a mixed number 1 3/20
