Given: mTP= 70°,m∠EPT = 54° Find: Angles of △SPT
Zigmanuir [339]

Answer:

The Angles of △SPT are

m\angle STP=35\°  

m\angle SPT=126\°

m\angle PST=19\°

Step-by-step explanation:

step 1

Find the measure of angle PET

we know that

The inscribed angle is half that of the arc it comprises.

m\angle PET=\frac{1}{2}(arc\ PT)

substitute the given values

m\angle PET=\frac{1}{2}(70\°)

m\angle PET=35\°

step 2

Find the measure of angle PTE

we know that

The sum of internal angles of a triangle must be equal to 180 degrees

In the triangle PET

m\angle PET+m\angle EPT+m\angle PTE=180\°

substitute the given values

35\°+54\°+m\angle PTE=180\°

m\angle PTE=180\°-89\°=91\°

step 3

Find the measure of angle STP  

we know that

The inscribed angle is half that of the arc it comprises.

m\angle STP=\frac{1}{2}(arc\ TP)

substitute the given values

m\angle STP=\frac{1}{2}(70\°)=35\°

step 4

Find the measure of angle SPT

we know that

m\angle SPT+m\angle EPT=180\° ----> by supplementary angles

m\angle SPT+54\°=180\°

m\angle SPT=180\°-54\°=126\°

step 5

Find the measure of angle PST

we know that

The sum of internal angles of a triangle must be equal to 180 degrees

In the triangle SPT

m\angle STP+m\angle SPT+m\angle PST=180\°

substitute the given values

35\°+126\°+m\angle PST=180\°

m\angle PST=180\°-161\°=19\°

What is the greatest common factor (GCF) of the numerator and denominator
pav-90 [236]

Answer:

C. x + 6

Step-by-step explanation:

Start by factoring completely the numerator and the denominator.

2x + 12 = 2(x + 6)

x^2 + 7x + 6 = (x + 1)(x + 6)

The only common factor is x + 6, so the GCF is x + 6

Please help I will rate the best answer and 5 star
Shkiper50 [21]

Answer:

f=6

g=8

Step-by-step explanation:

If ABCE is a trapezium, AD is parallel to BC, and angle C is a right angle, ABCD must be a rectangle. You know that since ABCE has an area of 60 and ABCD has an area of 48, ADE must have an area of 12. Because the area of a triangle is bh/2, AD must be 6 and therefore f must be as well. Since ABCD has an area of 48, g must be 48/6=8. Hope this helps!

If a rectangle is (x+2) wide and (x-7) in length, the area of the rectangle is? ​
Maru [420]

Answer: x² - 5x - 14

Step-by-step explanation: Start with the formula for the area of a rectangle.

Area = length x width

To multiply these two binomials, let's use the F.O.I.L. method.

The product of the first terms is x².

The product of the outer terms is -7x.

The product of the inner terms is 2x.

The product of the last terms is -14.

So we have x² - 7x + 2x - 14 which simplifies to x² - 5x - 14.
