Answer:

(3w - 7)(3w + 7)

Step-by-step explanation:

The expression is a difference of squares and factors in general as

a² - b² = (a - b)(a + b)

Thus

9w² - 49

= (3w)² - 7²

= (3w - 7)(3w + 7)

EASY QUICK POINTS!!!! Find the altitude of an equilateral triangle if each side of the triangle has the length of 6 meters!!!

KonstantinChe [14]

Answer:

5.20 to the nearest hundredth.

Step-by-step explanation:

The altitude line bisects the base of the triangle to form 2 right angled triangles with hypotenuse = 6 and the base = 3.

So, by the Pythagoras theorem the altitude is calculated as follows:

6^2 = 3^2 + x^2

x^2 = 36 - 9 = 27

x = √27

= 5.20 to the nearest hundredth.

Find the measure of Angle R to the nearest tenth. a. 63.8 degrees b. 67.2 degrees c. 70.9 degrees d. 61.5 degrees

Vikki [24]

The complete question in the attached figure

we know that
tan R°=opposite side angle R/adjacent side angle R
opposite side angle R=72 units
adjacent side angle R=25 units
so
tan R°=72/25
R=arc tan (72/25)---------> R=70.85°-------> R=70.9°

the answer is
R=70.9°
