<h3>The measure of angles of triangle are 96 degree, 36 degree and 48 degrees</h3>

<em><u>Solution:</u></em>

The ratio of the measures of the angles in a triangle is 8:3:4

Let the first angle be 8x

Let the second angle be 3x

Let the third angle be 4x

We know that,

sum of all angles in triangle is 180 degrees

Therefore,

8x + 3x + 4x = 180

15x = 180

x = 12

Thus,

First angle = 8x = 8(12) = 96

second angle = 3x = 3(12) = 36

third angle = 4x = 4(12) = 48

Thus measure of angles of triangle are 96 degree, 36 degree and 48 degrees

1 what is sum of the interior angles of ABCD what is the sum of the exterior angles of CHFE 3 which sides are parallel to CE 4 w
expeople1 [14]

Given that ABCD is a parallelogram, the sum of its interior angles is:
360°

<h3>What is a parallelogram?</h3>

A parallelogram is a rectilinear two-dimensional figure with four sides whose opposite sides are parallel. See the image attached.

<h3>What is the sum of the exterior angles of CHFE?</h3>

The sum of the exterior angles of any Triangle or any polygon is 360°. Hence, the sum of the exterior angles of CHFE (a polygon) is 360°.

<h3>Which sides are parallel to CE?</h3>

The sides that are parallel to CE are:

FH

AD and

<h3>IJ.

Which side is perpendicular to CE?</h3>

The side that are perpendicular to CE is side side HH, hence we can state that:

CE ⊥ EH, because both lines intersect each other at right angles.

<h3>What is the sum of ∠C and ∠H?</h3>

Because the sum of angles in a triangle is 180° and we already have ∠CEH to be equal to ∠90° hence,

∠C + ∠H? = 180° - 90°

= 90°

<h3>What is the measure of the exterior angles of a Regular Pentagon?</h3>

The measure of the exterior angles of a regular pentagon is 72°

Natalka [10]

Answer:

You can make 7 batches.

Step-by-step explanation:

Five and a half sticks of butter is equivalent to 22/4. 22 divided by 3 is 7 and 1/3, but 1/3 is not a full batch. Therefore you can make 7 batches.
