Find the measure of unknown angle​
Lemur [1.5K]

Answer:

Step-by-step explanation:

z = 102 degree (opposite angles of a parallelogram are equal)

z + x + 34 = 180 degree 9sum of adjacent angles of a parallelogram is 180 degree)

102 + x + 34 = 180

x = 180 - 136

x = 44 degree

y + 102 + x = 180 degree (sum of interior angles of a triangle is 180 degree)

y + 102 + 44 = 180

y = 180 - 146

y = 34 degree

how do I figure out the weight loss of tina? she lost 3 pounds on the first week of her diet. she gained a pound on the second w
hram777 [196]
1st week - Lost 3 pounds = +3 
2nd week - Gained 1 pound = -1    
3+13 = + 22       

So 22+3 = 25                 25-1 = 24 

So Tina lost 24 pounds in 13 weeks.

A triangle was dilated by a scale factor of 6. If sin aº
Pavlova-9 [17]

Answer:

24 units

Step-by-step explanation:

A triangle was dilated by a scale factor of 6. If sin a° = four fifths and segment DE measures 30 units, how long is segment EF?

triangle DEF in which angle F is a right angle, angle D measures a degrees, and angle E measures b degrees

15.5 units

24 units

30 units

37.5 units

From the description:

angle D measures a degrees

opposite to angle D is side EF

side DE (which measures 30 units) is the hypotenuse of the triangle.

We also know that

\sin (a) = \frac{4}{5}

\sin (a) = \frac{opposite}{hypotenuse}

From definition:

\sin (a) = \frac{opposite}{hypotenuse}

Replacing:

\frac{4}{5} =\frac{ EF}{DE} \\\\EF = \frac{4}{5} *DE\\\\EF = \frac{4}{5} *30 \\\\= 24 units

A cone has a volume of 226.08 cubic millimeters and a height of 6 millimeters. What is its
dezoksy [38]

Answer:

r≈5.36656314

Step-by-step explanation:

Since A=πr(r+\sqrt{h^2+r^2}) so we get that 226.08/pi≈72 or 226.08/3.14=72 we then plug it in to get 72=r(r+\sqrt{36+r^2}) so we get r≈5.36656314
