Answer:

Step-by-step explanation:

If a quadrilateral is inscribed in a circle, the opposite angles add to 180°.

Therefore:

$83^o+y^o=180^o$ subtract 83° from both sides

$83^o-83^o+y^o=180^o-83^o\\\\y^o=97^o$

Calculate x Give your answer correct to 1 d.p. Х 35° 15 cm it is a trigonometry question.

OlgaM077 [116]

Here we are finding x, given the angle and adjacent side. To find x we will use the function cos as cos = a/h.

So let's do cos(35°) = 15cm / x

cos(35°) = 0.8 (1 dp)

x = 15 cm / cos(35°)

x = 18.3 cm (1 dp)

In right triangle ABC, ZC is a right angle, m ZA = 52, AC = 10.01, and AB = c.

nlexa [21]

Answer:

The measurement of AB is 16.25 units.

Step-by-step explanation:

In right triangle ABC, ∠C is a right angle, m∠A = 52° , AC = 10.01, and AB = c.

We need to find the measurement of AB.

∠C is a right angle, it means AB is hypotenuse.

In a right angle triangle,

$\cos \theta=\dfrac{Base}{Hypotenuse}$

$\cos A=\dfrac{AC}{AB}$

$\cos (52^\circ)=\dfrac{10.01}{c}$

$0.616=\dfrac{10.01}{c}$

$c=\dfrac{10.01}{0.616}$

$c=16.25$

Hence, the measurement of AB is 16.25 units.

Divide. Write the quotient in lowest terms. 1/4 ÷ 1 1/8

natta225 [31]

Answer:2/11

Step-by-step explanation:

A fraction is in simplest form when the top and bottom cannot be any smaller

Firstly start by getting the common factors between 1 and 4 in 1/4 and 11 and 8 in 11/8. The common factor is 1 in 1/4 and 1 in 11/8. 1÷1/4÷1= 1/4. 11÷1/8÷1 = 11/8.

1/4÷ 11/8 =2/11.
