Two angles of a quadrilateral measure 215° and 70°. The other two angles are in a ratio of 2:13. What are the measures of those

Aleks04 [339]

The sum of the interior angles of a quadrilateral is 360°.

The ratio of 2 angles is 2 : 13. Take them as 2x° & 13x°.

Now, solve for x.

$\mathfrak{215+70+2x+13x=360}$

$\mathfrak{285+15x=360}$

$\mathfrak{15x=360-285}$

$\mathfrak{15x=75}$

$\mathfrak{x=\dfrac{75}{15}}$

$\underline{\mathfrak{x=5}}$

So,

2x = 2(5) = $\boxed{\mathfrak{10^{\circ}}}$

13x = 13(5) = $\boxed{\mathfrak{65^{\circ}}}$

$\mathbb{MIREU}$

One night, it is 24LaTeX: ^\circ

tatuchka [14]

Answer:

$T^\circ = -12^\circ$

Step-by-step explanation:

Given

Represent the temperature in Tucson with T and that in Minneapolis with M.

From the first statement, we have:

$T^\circ = M^\circ - 24^\circ$

From the second, we have:

$T^\circ = -M^\circ$ or $M^\circ = -T^\circ$ --- i.e. both are opposite numbers

Required

Find T

To calculate T, substitute -T for M in $T^\circ = M^\circ - 24^\circ$

This gives:

$T^\circ = -T^\circ - 24^\circ$

Collect Like Terms

$T^\circ +T^\circ =- 24^\circ$

$2T^\circ =- 24^\circ$

Make T the subject

$T^\circ =- 24^\circ/2$

$T^\circ = -12^\circ$

Hence, the temperature in Tucson is $-12^\circ$
