If im not mistake i think 1/2 is 0.5 but im not sure about the other one
Answer:
Your correct, it's C and D
Step-by-step explanation:
A and E are right triangles, so that's not the answer. B and F are isosceles triangles so that's not the answer. C and D are 2 DIFFERENT obtuse triangles so that's why C and D are the answers.
Ok, so the set up would be 3x+8 = 5x-40. If you solve for x you can then enter it into the equation and get your answer.
So subtract 3x from 3x and 5x. That leaves you with 8 = 2x-40
Next, you add 40 to both sides leaving you with 48 = 2x
Now divide 2 from x and 48 which give x = 24
Enter the value of x into the equation 3x+8
3(24)+8
80
And because we know it is an acute angle, angle ABC = 80 degrees
Answer:
Step-by-step explanation:
8x-192=96
8x-192+192=96+192
8x=288
8x/8=288/8
x=288/8
36
