∆ABC and ∆FDE are congruent by the SSS criterion.

x + 3 = 14 |subtract 3 from both sides

x = 11

subtitute the value of x to the equation x - y = 3

11 - y = 3 |subtract 11 from both sides

-y = -8 |change the signs

y = 8

Answer: x = 11 and y = 8.

He attempted 500 passes since you divide 350 by 7 which, would give you 5 then, you would multiply it by 100 therefore, it gives you 500

Find the measure of the numbered angles in rhombus ABCD

sasho [114]

Answer:

see the explanation

Step-by-step explanation:

we know that

In a Rhombus opposite angles are congruent and consecutive angles are supplementary

The diagonals are perpendicular and bisect the angles

step 1

Find the measure of angle 4

we know that

$m\angle 4=27^o$ --->by the diagonals bisect the angles

step 2

Find the measure of angle 1

we know that

$m\angle 1=27^o$ ----> by opposite angles are congruent

step 3

Find the measure of angle 2

we know that

$m\angle 1=m\angle 2$ ----> by the diagonals bisect the angles

$m\angle 2=27^o$

step 4

Find the measure of angle 3

we know that

$m\angle 3=90^o$ ----> by the diagonals are perpendicular

step 5

Find the measure of angle 5

we know that

$m\angle 5+27^o=90^o$ ----> by complementary angles

$m\angle 5=90^o-27^o=63^o$

step 6

Find the measure of angle 6

we know that

$m\angle 6=m\angle 5$ ----> by the diagonals bisect the angles

$m\angle 6=63^o$

Please help because I'm getting confused, and please show step by step. :(

Westkost [7]

So lets just simplify them first
1 batch = 2 3/4 so...
11/4 cups

and you need to make 3 1/2 batch so..
7/2 batch

then you just multiply it...
11/4 x 7/2
=77/8
=9 5/8

so you will need 9 5/8 cups
