True or False? In an isosceles trapezoid the diagonals are congruent.

1 answer:

3 0

It is true, they are congruent by doing a proof. You have to divide the trapezoid into 2 equal triangles. Then you can prove it. They are congruent since corresponding parts of congruent triangles are congruent.

you practice the piano for 30 min. each day. Write and solve an equation to find the total time t you spend practicing the piano

Tom [10]

Lets get all the information we need first.
A week has 7 days, you practice 30 min each day, so in a week you will practice a total time t of 30 min for 7 times, that is:
t = 7day(30 min/day)
t = 210 min
So in a week you will practice a total of 210 minutes.

Answer:

x = 14 D

Step-by-step explanation:

(18x + 36) / 3 = 6x + 12

6x + 12 = -16 + 8x

-6x . -6x

12 = -16 + 2x

+16 . +16

28 = 2x

/2 . /2

14 = x

If m<1=6x+50 and m<2=4x+40 find x

Pepsi [2]

$\text{Adjacent angles on a straight line sum up to 180} \textdegree$

$\text{Therefore }\measuredangle 1 + \measuredangle 2 = 180 \textdegree$

$\text {Since } \measuredangle 1 = 6x+50 \text { and } \measuredangle 2 = x+40$

$(6x+50) + (4x+40) = 180$

$6x+50 + 4x+40 = 180$

$10x+90 = 180$

$10x = 180 - 90$

$10x = 90$

$x = 9$

Answer: x = 9
