What is the value of y?<br><br><br><br> Enter your answer in the box.<br><br> y =

Olenka [21]

Answer:

$y=40\°$

Step-by-step explanation:

we know that

An isosceles triangle has two equal sides and two equal angles

The two equal angles are called the base angles and the third angle is called the vertex angle

In this problem the triangle ABC is an isosceles triangle

so

$AB=AC$

$5x=40\°$

$x=8\°$

The sum of the internal angles of a triangle is equal to $180\°$

so

Find the value of y

$(2y+20)\°+2(40\°)=180\°$

$2y=180\°-20\°-80\°$

$2y=80\°$

$y=40\°$

For circle O, mCD=125° and m

Burka [1]

CA is a diameter of the circle, so $m\widehat{AC}=180^\circ$ , which means $m\angle AOB=m\angle AOD=m\widehat{AD}=180^\circ-m\widehat{CD}=55^\circ$ . Then $m\boxed{\angle ABO}=90^\circ-55^\circ=35^\circ$ .

This means $m\angle CBO=55^\circ-35^\circ=20^\circ$ . Also, if $m\angle AOB=55^\circ$ , then $m\angle BOC=180^\circ-55^\circ=125^\circ$ , which in turns tells us that $m\boxed{\angle BCO}=180^\circ-20^\circ-125^\circ=35^\circ$ .

Work out the volume of a sphere please help i’ll give u brainlest

Doss [256]

Answer:

V = 3591.4 cm³

Step-by-step explanation:

Volume of Sphere = $\frac{4}{3} \pi r^3$

Where r = 9.5 cm

V = $\frac{4}{3} (3.14)(9.5)^3$

V = $\frac{4}{3} (3.14)(857.4)$

V = $\frac{10774}{3}$

V = 3591.4 cm³
