If the angle of a triangle are in the ratio 1:2:3, determine the 3 angles

BigorU [14]

Answer:

The angles are : 30° , 60° , 90°

Step-by-step explanation:

Sum of angles in a triangle = 180°

Given: the angles are in the ratio = 1 : 2 : 3

Sum of the ratio = 6

Therefore , the angles are

$first \ angle = \frac{1}{6} \times 180^\circ = 1 \times 30 = 30^\circ\\\\second \ angle = \frac{2}{6} \times 180^\circ = 2 \times 30 = 60^\circ\\\\third \ angle = \frac{3}{6} \times 180^\circ = 3 \times 30 = 90^\circ$

GrogVix [38]

Answer:

38 cm

Step-by-step explanation:

The perimeter of a rectangle is given by

P =2(l+w)

P =2( 2x+1 + x)

Combine like terms

P = 2(3x+1)

Distribute

P = 6x+2

Let x=6

P = 6*6+2

= 36+2

= 38 centimeters

Michaela spent 0.25 of her monthly allowance on transportion,3/8 of it on food and saved $18.27. How much was her allowance?

m_a_m_a [10]

Step-by-step explanation:

0.25 = one quarter - 2/8

3/8 is spent on food

so this leaves 3/8 for savings

therefore we know that $18.27 is 3/8 of her total allowance

18.27 ÷ 3 = 6.09

6.09 × 8 = 48.72

thus her total allowance must have been $48.72
