Answer:
true, false, true
Step-by-step explanation:
it only changes the direction
So if QR and PQ are the same ( which they are bc the angles and other sides are the same) 3n-1= 5n-7 so -1= 2n -7 so 6 = 2n so n = 3 then QR is 5n -7 so 5 x 3 is 15-7 is 8 so the answer is 8. Hope this helps :)
First you have Define the area of the total shape. Next you'd have to find the area of the unshaded shapes. then you would multiply in that area by floor because there for unshaded boxes. finally you subtract each box from the total area to get an answer of 3x - 4
Answer:
55.2° ≤ c ≤ 55.8°
Step-by-step explanation:
We know a + b + c = 180
Let's take the smallest value of a and b and find largest value of c:
51.3 + 72.9 + c = 180
c = 55.8
Now,
Let's take the largest value of a and b and find smallest value of c:
51.5 + 73.3 + c = 180
c = 55.2
Thus, we can say, range of c is:
55.2° ≤ c ≤ 55.8°
