The answer is going to be 15
Answer:634 cm and i think you add the something and a 3
Step-by-step explanation:
Photo math
Sum = adding correct.
That means we need to add 7+5 =12
and add the /8 to it
12/8
But thats improper so we need to simplify.
1 4/8
But theres still some simplifying.
4/8=1/2
That means your answer is 1 1/2
Hope this helped :)
Answer:
m∠A = 20°
Step-by-step explanation:
Given that the sum of the angles of any triangle is 180°, adding the expressions of each angle and setting them equal to 180° will give the value of 'x' and allow you to evaluate the angles.
2x + 5x + 11x = 180
18x = 180
18x/18 = 180/18 or x = 10
m∠A = 2x or 2(10) = 20°
m∠B = 5x or 5(10) = 50°
m∠C = 11x or 11(10) = 110°
Out of the choices given, the only one that is true is that m∠A = 20°.
4(d-1), if you expand it gets 4d-4.
