Can somone help me with this 1 problem? In the figure shown, △RST is an isosceles triangle with RS≅RT. Which is the measure of ∠
anastassius [24]
In an isosceles triangle, the angles opposite to the two equal sides are also congruent.
Based on your information, T and S are congruent. So we know that the measure of angle T is 3x+7. But we need to solve for x. Let's add all the angle values together and set it to 180 because the angles of a triangle sum to 180.
1) 2(3x+7) + 2x - 2 = 180
2) 6x + 14 + 2x - 2 = 180
3) 8x + 12 = 180
4) 8x = 168
5) x = 21
6) m<T = 3x + 7 = 3(21) + 7 = 63 + 7 = 70
I got C, but it is always helpful to double check work. Hope this helps!

Yuki888 [10]

Answer:

Step-by-step explanation:

a) Si se suman las probabilidades de venta, es decir:

Probabildad de vender 0 auto ( es decir que no vendió) = 0,19

Probabildad de vender 1 auto                                              = 0,38

Probabildad de vender 2 autos                                            = 0,29

Probabildad de vender 3 autos                                            =0,15

Da por resultado:  1,01

1,01 > 1  

Ninguna probabilidad puede ser mayor que

b) LLover y no llover son condiciones excluyentes en relación al evento, es decir en relación a lluvia cualquier día o llueve o no llueve de tal forma

que las dos situaciones conforman el universo completo y deben sumar 1. en este caso el error s que suman 0.92 cando deberían sumar 1

c) No existen probabilidades negativas ( en este caso señalan -0,25 como una probabilidad

d) La probabilidad de sacar una carta de corazones es 1/4 (correcta pues hay la misma cantidad de carta de las cuatro viras  tipo ( diamante, trebo, corazones y el otro).

La mitad de las cartas son negras, de tal modo que 1/2 es correcto valor para esta probabilidad.

La probabilidad de que sea corazones y negra s 1/4*1/2  = 1/8

Luego no hay error en esta aseveración
