The isosceles triangle theorem says "If two sides of a triangle are congruent then the angles opposite those sides are congruent If you are using this figure to prove the isosceles triangle theorem, which of the following would be the best strategy

Answers

Answer:

(A) option A is correct that is draw TV so that V is the mid point of SU, then prove ΔSTV≅ΔUTV using SSS.

Step-by-step explanation:

From the given figure, it is given that ST=TU, then draw TV so that V is the mid point of SU, then, from

ΔSTV and ΔUTV

ST=UT (Given)

SV=UV (Definition of mid point)

TV=TV (Reflexive property)

Thus, by SSS rule

ΔSTV≅ΔUTV

Hence, by CPCTC, ∠S≅∠U which satisfies the isosceles triangle theorem that is "If two sides of a triangle are congruent then the angles opposite those sides are congruent".

Thus, option A is correct that is draw TV so that V is the mid point of SU, then prove ΔSTV≅ΔUTV using SSS.

One serving of this cereal provides you with 160 mg of sodium. This is 7% of your body's daily needs. How many milligrams of sodium equal 100%?

Answers

First, we see the closest multiple of 7 under 100 is 98 and that divided by 7 is 14. there are 2/7 as our remainder. We do 2/7 times 160 to get 320/7 and 320/7 = 45 and 5/7. We convert 5/7 into a decimal like 5/7 = .7. The answer is 45.7 milligrams of sodium.

On a car trip Sam drove m miles Kara drove twice as many miles as Sam and Darin drove 20 fewer miles than Kara in terms of m many miles did Darin drive

Answers

Answer:

Darin drove '2m - 20' miles.

Step-by-step explanation:

We are given that Sam drove 'm' no. of miles.

As, it is also given that Kara drove twice as many miles as Sam. Therefore we get that Kara drove '2m' no. of miles.

Now, it is given that Darin drove 20 miles fewer than Kara .i.e. Darin drove '2m - 20' no. of miles.

Hence, in terms of m, Darin drove '2m - 20' miles.

Dao has 2 3/8 pounds of hamburger meat. He is making 1/4 -pound hamburgers. Does Dao have enough meat to make 10 hamburgers? Explain.

Answers

To find if there is enough, here is the equation
$(1)/(4)$ × $(10)/(1)$
You multiple across
1×10=10 and 4×1=4= $(10)/(4)$
Then you divide the numerator(top) by the denominator(bottom)
10÷4= $2 (2)/(4)$ ⇒ $2(1)/(2)$
To see if they equal, you multiply just the fraction by four
$(1)/(2)$ × $(4)/(4)$ = $(4)/(8)$
Thus the answer is $2 (4)/(8)$ which is larger than $2 (3)/(8)$
Dao has enough meat to make 10 hamburgers because $2(4)/(8)$ > $2 (3)/(8)$
