The measures of one of the angles of a triangle is 35.The sum of the measures of the other two angles is 145 and the difference

jok3333 [9.3K]

Answer:

The measures of the angles are 65° and 80°

Step-by-step explanation:

One of the angles is 35°

We know that the other two angles have a difference of 15°

With this knowledge we can write an equation.

2x symbolizes the two angles

+15 symbolizes the difference between the two angles

145 = 2x + 15

145 - 15 = 130

2x = 130

x = 65

65 is the size of one of the angles.

Next, we add 15 to 65 and we get 80

80 is our second angle

(3y^0 x^2)^6 times y^-3 zx8

timurjin [86]

Ok so some basic rules

$(x^m)(x^n)=x^{m+n}$
$(ab)^c=(a^c)(b^c)$
$(x^m)^n=x^{mn}$
$x^0=1$
$x^{-m}= \frac{1}{x^m}$

so
$[(3y^0x^2)^6][y^{-3}zx^8]$
$[(3(1)x^2)^6][y^{-3}zx^8]$
$[(3x^2)^6][y^{-3}zx^8]$
$[(3^6)((x^2)^6)][y^{-3}zx^8]$
$[(3^6)(x^{12})][y^{-3}zx^8]$
$(3^6)(x^{12})(y^{-3})(z)(x^8)$
$(3^6)(x^{12})(x^8)(y^{-3})(z)$
$(3^6)(x^{20})(\frac{1}{y^3})(z)$
$\frac{3^6x^{20}z}{y^3}$
$\frac{729x^{20}z}{y^3}$
