Answer: 20 degrees

Step-by-step explanation:

Find the 180 (degrees angle)= angle CD

180 degrees-110 degrees= 70 degrees

By using the OAT (opposite angle theorem), the opposite of the angle OD (you know what i mean) will be 70 degrees too. So, Angle BO is 70 degrees too. We know the right angle there is 90 degrees because of the square sign so, create another 180 degrees angle but subtract 160 degrees (70+90) from 180 degrees which is 20 degrees.

If m<mkl=83. m<jkl=127. and m<jkm=(9x-10). find the value of x

kirza4 [7]

MKL = 83, JKL = 127, JKM = 9x - 10 given

JKL + MKL = JKM angle addition postulate

127 + 83 = 9x - 10 substitution

210 = 9x - 10 simplify (add like terms)

220 = 9x addition property of equality

$\frac{220}{9}$ = x

Find the radius pls. help

MA_775_DIABLO [31]

Good morning,

Answer:

Step-by-step explanation:

V = h × (base area)

= 12 × (π×r²)

then 192π = 12π×r²

Then 192 = 12×r²

Then r² = 192÷12 = 16

Then r = √16 = 4.

3) Margarita manejó 429 km: 42 en la ciudad y el resto, en la autopista.

12345 [234]

Answer:

Margarita gastó $40.43.

Step-by-step explanation:

Tenemos la siguiente información.

km recorridos por Margarita

42 km - ciudad

387 km - autopista

Rendimiento del carro

1 galon cada 28 km - ciudad

1 galon cada 36 km - autopista

Hacemos el siguiente factor de conversión

Ciudad

$42 km \times \frac{1\: galon}{28\: km}=1.5\: galones$

Autopista

$387 km \times \frac{1\: galon}{36\: km}=10.75\: galones$

Ahoa, se sabe que 1 galon cuesta $3.30. Por lo tanto, el costo de viaje será:

Total galones = 1.5 + 10.75 = 12.25 galones

Total costo = 3.30*12.25 = $40.43.

Espero te haya servido!
