Answer: 17

Step-by-step explanation:

We are told Jason has 34 strawberry scones and 85 raspberry scones and that he wanted to make as many identical bags of scones as possible and that each bag should have an equal number of strawberry scones and an equal number of raspberry scones.

To calculate greatest number of bags Jason can fill, we find the factor of 34 and 85 and choose the highest that's common to both.

Factor of 34 = 1, 2 , 17, and 34

Factor of 85 = 1, 5, 17, and 85.

Highest common factor = 17

The answer is 17

Given: AB ∥ DC

RSB [31]

Answer:

$A=1,720.16\ units^2$

Step-by-step explanation:

we know that

The area of the trapezoid is equal to

$A=\frac{1}{2}(DC+AB)DE$

step 1

Find the measure of angle DAE

m∠ADC+m∠DAE=180° -----> by consecutive interior angles

we have

m∠ADC = 134°

substitute

134°+m∠DAE=180°

m∠DAE=180°-134°=46°

step 2

In the right triangle ADE

Find the length side AE

cos(∠DAE)=AE/AD

$AE=cos(46\°)(40)\\AE=27.79\ units$

step 3

In the right triangle ADE

Find the length side DE

sin(∠DAE)=DE/AD

$DE=sin(46\°)(40)\\DE=28.77\ units$

step 4

Find the area of ABCD

$A=\frac{1}{2}(DC+AB)DE$

we have

$DC=32\ units\\AB=DC+2(AE)=32+2(27.79)=87.58\ units\\DE=28.77\ units$

substitute

$A=\frac{1}{2}(32+87.58)28.77$

$A=1,720.16\ units^2$
