the triangle could only be proven isosceles if it was proven or given that SP = SR or thatangles PQS = RQS otherwise the reasoning is incomplete

What is the measure of a base angle of an isosceles triangle if the measure of the vertex angle is 38 and the two congruent side

Harrizon [31]

Bearing in mind that an isosceles triangle has twin sides, and coming out of the vertex they make twin angles at the base, check the picture below.

In order to use a ladder safely, the angle that the ladder forms with the ground should not exceed 70 degree. If you have a ladd

solong [7]

Answer:

Maximum safe height can be reached by ladder = 15.03. ft

Step-by-step explanation:

Given,

Let's assume the maximum safe height of wall = h

angle formed between ladder and ground = 70°

length of ladder = 16 ft

From the given data, it can be seen that ladder will form a right angle triangle structure with the wall

So,from the concept of trigonometry,

$Sin70^o\ =\ \dfrac{\textrm{maximum safe height of wall}}{\textrm{length of ladder}}$

$=>Sin70^o\ =\ \dfrac{h}{16\ ft}$

$=>\ h\ =\ 16\times Sin70^o$

=> h = 16 x 0.9396

=> h = 15.03 ft

So, the maximum safe height that can be reached by the ladder will be 15.03 ft.

assume the situation can be exposed as a linear cost, find the cost function, fixed cost is $100, 40 items cost 1,200 to produce

alexira [117]

C(x) = 1200(40) + 100
or
= mx+c
where m = 1200, x = 40, y = 100

hope it helped,
click thx if it did.

At the end of a recent WNBA regular season, the Phoenix murmur had 12 more victories than losses. The number of victories they h

Hoochie [10]

Answer:

34 games

Step-by-step explanation:

let the number of losses be $l$

let the number of victories be $v$

the Phoenix murmur had 12 more victories than losses:

$v=l+12$

The number of victories they had was one more than two times the number of losses:

$v=2l+1$

We have 2 expressions for $v$ , equating these 2, we can solve for $l$ :

$l+12=2l+1\\12-1=2l-l\\11=l$

So 11 games, they lost.

Using this value, we can plug into the 1st equation to solve for v:

$v=l+12\\v=11+12\\v=23$

So 23 games, they won.

Given that no draws, they played a total of 23 + 11 = 34 games this season
