Answer:

add them all and put them equal to 180 cause all interiors angles of a triangle adds up to 180.

Step-by-step explanation:

x^2+6x+68=180

x^2+6x-112=0

(x-8)(x+14)

x=8

x^2+1=65

2x+24=40

4x+43=75

hence x^2+1 is your answer

Two diced are rolled. What is the probability that the sum of two numbers on the dice will be 4? 11/121/40

makkiz [27]

Each die has 6 possible outcomes (the numbers from 1 to 6).

If we roll two dices, the total number of outcomes is 6 * 6 = 36.

From these outcomes, the ones that have a sum of 4 are:

(1, 3), (2, 2) and (3, 1).

So, if we have 3 wanted outcomes from a total of 36, the probability is:

$P=\frac{3}{36}=\frac{1}{12}$

Therefore the correct option is the second one.

What is the 100th triangular number?

krek1111 [17]

Answer:

$T_1_0_0=5050$

Step-by-step explanation:

A triangular number is number that can be recomposed in the form of an equilateral triangle. Each triangular number is defined by:

$T_n=\frac{n^2+n}{2} \hspace{5} n\in N$

Hence, evaluating n=100

$T_1_0_0=\frac{(100)^{2}+100 }{2} =5050$

Help with Geometry needed!<br>For this figure, what is the value of X?

Finger [1]

Hello! A triangle has angles that sum up to 180°. So first off, let's solve for the angle of the other triangle. 83 + 31 gives us 114. 180 - 114 is 66. So the angle for the first triangle is 66°. The opposite angle would be the same. Finding the measurement of the other triangle gives us the measurement of x, because the angles are the same. So x = 66°.
