Answer:
40.5
Step-by-step explanation:
(n-2)*180
(7-2)*180=5*180=900
10p+135+149+121+90=900
10p=-495+900=405
p=40.5
Answer:
a) (x + 14) + 3x = 90
b) m<1 = 33 degrees
m<2 = 57 degrees
Step-by-step explanation:
a) as we can see, the measure of angle 1 added to the measure of angle 2 will give 90 degrees
Mathematically, we have this as;
m<1 + m<2 = 90
Using the values of the angles given, we have it that;
(x + 14) + (3x) = 90
x + 14 + 3x = 90
4x + 14 = 90
4x = 90-14
4x = 76
x = 76/4
x = 19 degrees
b) if x = 19; then ;
m<1 = (19 + 14) = 33 degrees
m<2 = 3(19) = 57 degrees
Answer:
The answer is 7 1/2 or 15/2 or 7.5 (all the same just in mixed fraction and decimal form)

Answer:
He is incorrect
Step-by-step explanation:
In 1.967, the hundredth is greater than 5. That means you'd round up! So, the correct answer would be 2.
