Question

please solve my problems I will mark as brainlist ​

Answer 1

Answer:

6)Angles a° and c° are also vertically opposite angles, so must be equal, which means they are 140° each. Answer: a = 140°, b = 40° and c = 140°.

Step-by-step explanation:

7)1000/250 = 4/1

8)375/10

9) 360 degree

6.) what is the measure of the vertically opposite angle of 140°.

Ans.) Vertically opposite angles are always equal to each other. So, the angle is 140° only.

${\boxed{\underline{\sf{ \pink{140 \degree}}}}}$

7.) Find the ratio between 3km and 1km 250m .

Ans.) First, convert 250 m to km.

$\sf{1m = \frac{1}{100} km}$

So, 250 m = 0.25km

Ratio of 3km and 1.25km

3 : 1.25

${\boxed{\underline{\sf{ \pink{12:5}}}}}$

8.) convert 37.5% into fraction.

Ans.) Removing % sign given 100 in divide.

$: \implies \: \frac{37.5}{100}$

Now, removing the decimal

$: \implies \sf{ \frac{375}{1000}}$

$: \implies \sf{ \frac{125(3)}{1000}}$

$: \implies \sf{ \frac{ \cancel{125}.3}{ \cancel{125}.8} }$

${\boxed{\underline{\sf{ \pink{ \frac{3}{8} }}}}}$

9.) write angle sum property of quadrilateral.

Ans.) As a quadrilateral has 4 angles. So the sum of all the angles is 360°.

$\sf{ \angle \: abc + \angle \: bcd \: \angle \: cda + \angle \: dab = 360 \degree}$

${\boxed{\underline{\sf{ \pink{ 360 \degree }}}}}$
