Very stuck 20 points abcd is a parallelogram with diagonal ac. if the measure of angle cab is 24° and the measure of angle adc is 127°, what is the measure of angle dac? parallelogram abcd with diagonal ac; the measure of angle adc is 127 degrees, and the measure of angle cab is 24 degrees.
a) 29°
b)48°
c)79°
d)103°

A) 29°

Step-by-step explanation:

Since the sum of adjacent angles of the triangle = 180°

thus, the sum of ∠ DAB + ∠ADC = 180°

Also, ∠ADC = 127°

Thus, ∠DAB = 180° - ∠ADC = 180 - 127 = 53°

Also, ∠CAB = 24°

∴ ∠DAC = ∠DAB - ∠CAB

⇒ ∠DAC = 53° - 24° = 29°

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.
