Dividing using long division would be 156 r 3, I believe.

783/5=156 r3

Take 5 and divide it with every digit, and what you have left subtract and go on with the next digit.

Need help finding measure of angle R.

Answer:

B.) 113°

Step-by-step explanation:

In the isosceles trapezoid, angles T and S are congruent. Find the value of x:

$4x+7=7x-38$

Subtract 4x from both sides:

$4x-4x+7=7x-38-4x\\7=3x-38$

Add 38 to both sides:

$7+38=3x-38+38\\45=3x$

Divide both sides by 3:

$\frac{45}{3}=\frac{3x}{3}\\\\ 15=x\\\\x=15$

x is equal to 15. Now substitute the value of x into the one of the expressions:

$4(15)+7\\60+7\\67$

$7(15)-38\\105-38\\67$

The angles T and S are 67°.

The angles of a trapezoid will always add up to a total of 360°, so add the angles T and S:

$67+67=134$

Subtract their total from 360:

$360-134=226$

The total of the angles Q and R is 226°. Since this is an isosceles trapezoid, those two angles are also congruent. Divide the value by 2:

$\frac{226}{2}= 113$

Angle R is 113°.

Done.

Evaluate the expression 3.14(a2 + ab) when a = 3 and b = 4. (Input decimals only, such as 12.71, as the answer.)

raketka [301]

Replace a and b with the given values:

3.14(3^2 + 3x4)

Simplify:

3.14(9 +12)

3.14(21)

Multiply:

3.14 x 21 =65.94

The number 17 is increased to 19. What is the percentage by which the number was increased, to the nearest tenth of a percent?

S_A_V [24]

19/17 = ?/100 19 multiplied by 100 is 1900 then divide by 17 which is 111.76..., round it = 111.8%
