Answer:

No because the bottom one is an acute triangle but the top one is obtuse.

Hope this helped! :3

Answer:

Hi there!

The answer to this question is: yes they're indeed similar

Step-by-step explanation:

As you can see both triangle have 30 degrees on the bottom corner of the triangle.

Then if you look at triangle ABC, they give you angle ACB which is 65 degrees. Using the triangle sum theorem you can figure out the measure of the last angle is 85. This angle corresponds with angle FED on the smaller triangle. Then if you look at both side AC and side FD they are half each others length therefore they are similar

Make a the subject of a2+b2=c2

wel

Answer:

$a=\sqrt{c^2-b^2$

⇒ $a=\sqrt{(c+b)(c-b)}$ [Factorized form]

Step-by-step explanation:

Given expression:

$a^2+b^2=c^2$

We need to make $a$ the subject.

In order to do that we need to solve the expression for $a$ in terms of $b$ and $c$

We have,

$a^2+b^2=c^2$

Subtracting both sides by $b^2$

$a^2+b^2-b^2=c^2-b^2$

$a^2=c^2-b^2$

Taking square root both sides in order to remove square of $a$

$\sqrt{a^2}=\sqrt{c^2-b^2}$

$a=\sqrt{c^2-b^2$

The difference of squares can be factorized and written as:

$a=\sqrt{(c+b)(c-b)}$ [difference of squares $x^2-y^2=(x+y)(x-y)$ ]

Emanuel was charged \$32$32dollar sign, 32 for a 14\dfrac29 \text{ km}14

Degger [83]

Answer:

2.25

Step-by-step explanation:

because you have to divide 32 by 14 2/9 resulting in the the 14 2/9 to be 128/9 and then flipped, 9/128. Afterwards, cross out the the 32 and 128 since 32 is a factor of 128 to get 1 and 4.Then apply mutiplication 1/1 * 9/4= 9/4 or 2 1/4= 2.25

Can y’all please explain this to me, I know the answer but I don’t know how to get it thanks

Answer:

250 jars

6 hours

Step-by-step explanation:

We know they make 50 jars in an hour, so 50 times 5 is 250 jars in 5 hours. Since 300 is 50 more than 250, and we know 50 times 6 is 300, we can say that we would need 6 hours to make 300 jars.
