The area of the triangle is 5.88 square centimeters.what is the length of the base.the heights is 2.1
Bas_tet [7]

Answer:

base = 5.6 cm

Step-by-step explanation:

area of a triangle = 1/2 * base * height

area = 5.88 cm²

height = 2.1 cm

5.88 = 1/2 * base * 2.1

5.88 = 1.05 base

5.88 / 1.05 = base

base = 5.6 cm

Please help im not very sure what any of this means
BaLLatris [955]

Answer:

∠JKH and ∠GHF

Step-by-step explanation:

<em>hey there,</em>

<em />

< Corresponding means "the angles which occupy the same relative position at each intersection where a straight line crosses two others. If the two lines are parallel, the corresponding angles are equal." The lines here are parallel so they are equal.

If you don't understand the meaning of the angles also, feel free to ask me about that too.

The two angles I listed are equal to equal to each other. When you look at the other options, they aren't equal, they might look less or more degrees.

If this won't be a multiple choice but short answer, try looking at angles that look similar and see if they would be able to match with the angle given. >

<u>Hope this helps! Feel free to ask anything else.</u>

Will give brainliest to first correct answer! find missing length
Rudiy27

Answer: 6

Step-by-step explanation:

They are similar triangles so they have proportionality

For the small triangle the side is 2 and the hypoteneuse is 4, for the large triangle the side is 5 so the entire hypoteneuse is 10. 10-4 = 6 which is the missing side

For the following geometric sequence find the recursive formula: {-1, 3, -9, ...}.
vredina [299]
First term (a1) is -1

recursive formula goes like this

a_n is the nth term
a_{n-1} is the term before that

we normally have a_n=f(a_{n-1})

we see each term is multipying by -3 to get next one


so that would be
a_n=-3*a_{n-1} where a1=-1


the 3rd option is correct except that it is the explicit formula

so answer is 2nd one
