The length of each square on the grid represents 1 cm. The scale

Mathematics
1 answer:
tatyana61 [14]3 years ago
5 0

Answer:

Step-by-step explanation:

Length of the rectangle given in the the figure attached = 2 cm

Width of the rectangle = 5 cm

Scale used, 24 in to 1 cm

Therefore, length of actual rectangle = 2×24 = 48 in

width of the actual rectangle = 5×24 = 120 in

Now we have to draw a drawing by using the scale,

16 inches to 1 cm

Or 1 inch = \frac{1}{16} cm

Therefore, length of the rectangle drawing = 48\times \frac{1}{16}

                                                                        = 3 cm

Similarly, width of the rectangle drawing = 120\times \frac{1}{16}

                                                                    = 7.5 cm

Crazy boy [7]

Answer:

x= -30

Step-by-step explanation:

√3×sinx+cosx=0

√3sinx=-cosx

√3sinx/-cosx=1

-sinx/cosx=1/√3

-tanx=1/√3

(tan(180-30))=1/√3

tan(-30)=1/√3

Therefore, x= -30

Maths help PLZZ!!!

Triangle ABC is an isosceles triangle.

Solution:

Given data:

∠ABC = 70° and ∠ACD = 55°

<em>If two parallel lines are cut by a transversal, then alternate interior angles are congruent.</em>

m∠BAC = m∠ACD

m∠BAC = 55°

<em>Sum of the angles in a straight line add up to 180°.</em>

m∠ACD + m∠ACB + m∠ABC = 180°

55° + m∠ACB + 70° = 180°

m∠ACB + 125° = 180°

Subtract 125° from both sides, we get

m∠ACB = 55°

In triangle ABC,

∠BAC = 55° and ∠ACB = 55°

∠BAC = ∠ACB

Two angles in the triangle are equal.

Therefor triangle ABC is an isosceles triangle.
