Step-by-step explanation:
The length of a side of an equilateral triangle is x−4.5.
First, express its perimeter as a sum.
Next, express its perimeter as a product.
Answer:
The sides of an equilateral triangle are same. So if one of the sides is (x-4.5), all the sides are (x-4.5).
Let the sides are a=(x-4.5), b=(x-4.5), c=(x-4.5)
1. Perimeter(as sum) = a+b+c
= (x-4.5)+(x-4.5)+(x-4.5)
= x+x+x-4.5-4.5-4.5
= 3x - 13.5
2. Perimeter (as product) = 3×a
= 3×(x-4.5)
= 3×x - 3×4.5
= 3x - 13.5
(you can write 3×b or 3×c also as a=b=c.)
Both perimeter as sum and perimeter as product are same as adding a number three times is the same as multiplying it by 3.

In ΔOPQ, \overline{OQ} OQ is extended through point Q to point R, \text{m}\angle PQR = (4x-10)^{\circ}m∠PQR=(4x−10) ∘ , \text{m}\angle OPQ = (x+9)^{\circ}m∠OPQ=(x+9) ∘ , and \text{m}\angle QOP = (x-5)^{\circ}m∠QOP=(x−5) ∘ . Find \text{m}\angle PQR.m∠PQR.
Answer:
In
In to point R, \text{m}\angle PQR = (7x-19)^{\circ}m∠PQR=(7x−19) ∘ , \text{m}\a
Step-by-step explanation:
The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length thus m∠PQR will be 18°.
What is an angle?An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
In any triangle,The sum of two interior angles other than the adjacent angle of extended length will be equal to the external angle of extended length.
In the given triangle below image,
m∠PQR = m∠OPQ + m∠POQ
4x - 10 = x + 9 + x - 5
4x - 10 = 2x + 4
2x = 14
x = 7
So,
m∠PQR = 4(7) - 10 = 18°
Hence "The measure of m∠PQR will be 18° for the given triangle".

17 is 50% of what number?
Answer: 34
Step-by-step explanation:
therefore, the answer to "17 is 50 percent of what number?" is 34, and you can also derive that 50 percent of 34 equals 17
Answer:
34
Step-by-step explanation:
This is a fairly simple problem. If 17 is 50% of something, that means it's half of something. That means to multiply 17 times 2, and you get 34.
