URGENT!!!! A ladder is leaning up against a house at a 49∘ angle. Jim, who is 5 feet tall, is standing upright on the ladder for

CaHeK987 [17]

Answer:

6.5 feet

Step-by-step explanation:

Based on the Cosines Law, we have:

$cos(B) = \frac{c^{2} + a^{2} - b^{2} }{2 * a * c}$

If we isolate b (which is our x in this problem), we have

$b = \sqrt{a^{2} + c^{2} - 2 * a * c * cos(B)}$

We have

a: 2

c: 5

B: 131 (since it's the complement of the 49 degrees angle: 180 - 49).

So, we plug these numbers in the formula....

$b = \sqrt{2^{2} + 5^{2} - 2 * 2 * 5 * cos(131)} = 6.49$

We round it up to the tenth of the unit... to get 6.5

Given that ABCD congruent to PQRS, solve for m<br><br><br> A.0.5<br> B.2.5<br> C.3<br> D.5

34kurt

As the 2 quadrilaterals are congruent the sides of one quadrilateral are equal to the corresponding sides of the other quadrilateral
Hence,
AB = PQ
RQ = BC
AD = PS
DC = RS
Since terms for both AB and PQ are given we can equate the terms and find m
5m -9 = m + 11
5m -m = 11 + 9
4m = 20
m = 5
Correct answer is D , 5

Aileen has 10 apples. How many apples will there be in 7 boxes?

Marysya12 [62]

The answer should be 1 because you can’t box up pieces of apples to divide it perfectly into a box. It matters that each box has a full apple!! Hope this makes sense!!
