If A ABC ~ ARST and m 2 A = 42°, m 2 C = 60°, find the measure of < S.

Free_Kalibri [48]

Answer:

Step-by-step explanation:

∠A + ∠B + ∠C = 180 { Angle sum property of triangle}

42 + ∠B + 60 = 180

∠B + 102 = 180

∠B = 180 - 102 = 78

In similar triangles, corresponding angles are congruent.

∠S ≅ ∠B

∠S = 78°

1. La suma de dos números es 115. El número mayor es dos veces más 22 unidades que el otro. Hallar

Lerok [7]

De acuerdo con un sistema de ecuaciones, tiene-se que los números son 31 y 84.

----------------

En el sistema de ecuaciones, tiene-se que los números son x e y.
Suma de 115, o sea, $x + y = 115$
El número mayor es dos veces más 22 unidades que el otro, o sea, $x = 2y + 22$

----------------

Primero se encuenta el número menor, reemplazando la segunda ecuación en la primera:

$x + y = 115$

$2y + 22 + y = 115$

$3y = 93$

$y = \frac{93}{3}$

$y = 31$

----------------

El número mayor es dado en función de el menor, o sea:

$x = 2y + 22 = 2(31) + 22 = 62 + 22 = 84$

Los números son 31 y 84.

For this problem, you would replace x with 7 then solve.

3/ (7+2) - sqrt(7-3) =

3/9 - sqrt(4) =

1/3 - 2 = -1 2/3 = -1.67

The lengths of the two sides of a triangle (not necessarily a right triangle) are 1.00 meters and 3.54 meters. The sine of the a

DerKrebs [107]

Answer:

sin B= 0.096288

B = 5.525°

Step-by-step explanation:

Consider ΔABC as shown in figure attached

From figure:

a = 1 m

b = 3.54 m

sin A = 0.0272

sin B = ?

Using the sine rule for non-right-angle triangle

$\\\frac{a}{sin\, A}=\frac{b}{sin\,B}\\\\sin\,B=\frac{b(sin\,A)}{a}\\\\sin\,B=\frac{(3.54)(0.0272)}{1}\\\\sin\,B=0.096288\\\\B= 5.525^o$
