What angle is this and explain
REY [17]

The measures of the angles are 59 degrees

<h3>How to determine the value of the angles?</h3>

The angles are given as:

Angle 1 = 2x + 17

Angle 2 = 3x - 4

By the interior angle theorem, the angles are congruent

So, we have

Angle 1 = Angle 2

Substitute the known values in the above equation

2x + 17= 3x - 4

Collect the like terms

3x - 2x = 17 + 4

Evaluate the like terms

x = 21

Substitute x = 21 in Angle 1 = 2x + 17

Angle 1 = 2 * 21 + 17

Evaluate

Angle 1 = 59

This means that

Angle 1 = Angle 2 = 59

Hence, the measures of the angles are 59 degrees

Help me please, its due at night today!!!
postnew [5]

Answer:

Step-by-step explanation:

Area of polygon = area of square + area of triangle

Square:

Side = 12 cm

Area of square  = side *side

                          = 12 * 12

                          = 144 sq.cm

Triangle:

base (b) = 12 cm

Height h = 19 cm

Area =\frac{1}{2}bh\\\\=\frac{1}{2}*12*19\\

= 6 * 19

= 114 sq.cm

Area of polygon = 144 + 114 = 258 square cm

Which represents the polynomial written in standard form? 4m – 2m4 – 6m2 + 9 9 + 4m + 2m4 – 6m2 2m4 – 6m2 – 4m + 9 9 – 6m2 + 4m
Alenkasestr [34]

Answer:

- 2m^4 - 6m^2 + 4m  + 9

Step-by-step explanation:

Given

4m - 2m^4 - 6m^2 + 9

Required

Express in standard form

To do this, we simply reorder the terms of the polynomial in descending order of power.

So, we have:

- 2m^4 - 6m^2 + 4m  + 9

Step-by-step explanation:

inverse of 5= 1/5

swap the variables: y=10−5k becomes k=10−5y

Now, solve the equation k=10−5y

for y

y=−k/5+2
