What is the measure of a base angle of an isosceles triangle if the measure of the vertex tangle is 38 degrees and the two congr
Anit [1.1K]

The measures of the angles of the isosceles triangle are 55, 55 and 70.

Explanation:

An isosceles triangle has two congruent base angles and a vertex angle.

Let b =the measure of one of the base angles.

Let v = the measure of the the vertex angle.

The vertex angle is 40 degrees less than the sum of the base angles.

v = b + b − 40 = 2 b − 40

The sum of the measures of the angles of a triangle is 180.

b + b + v = 180

Substitute 2 b − 40 for v .

b + b + 2 b − 40 = 180

4 b − 40 = 180

+40+40

Combine like terms.

Add 40 to both sides.

4b=220

Divide by 4

4 b/4 = 220 /4

b = 55

v = 2 b − 40

v = 2 ( 55 ) − 40 = 70

12³.2².4⁴ / 4³.2.12²
Nuetrik [128]
Remember
\frac{xyz}{abc}=( \frac{x}{a} )( \frac{y}{b} )( \frac{z}{c} )
and
\frac{x^m}{x^n}=x^{m-n}

split them to have same bases
\frac{12^32^24^4}{4^32^112^2}=
( \frac{12^3}{12^2} )( \frac{4^4}{4^3} )( \frac{2^2}{2^1} )=
(12^1)(4^1)(2^1)=

15% of amount = 112.79
Mazyrski [523]
To find the original amount, you divide the product by the percentage. 

112.79 / 0.15 ≈ 751.933 (the 3's repeat infinitely). 

To check your answer, multiply 751.933 by 0.15. 
751.933 * 0.15 = 112.78995 ≈ 112.79
