Trigonometry Question PQR is a triangle with sides PQ=4cm, PR=6 cm and QR=3cm. Check whether the triangle is right angles or not?Give reasons for your answer..

Triangle is not a right angled triangle.

Step-by-step explanation:

PQ = 4cm, PR = 6 cm and QR = 3cm

According to the Pythagorean theorem, If it is a right angled triangle then the square of the longest side is equal to the sum of squares of other two sides.

here, longest side is PR.

As they are not equal so the triangle is not right angles triangle.

step-by-step explanation:

c = 0.429t

step-by-step explanation:

the constant rate at which carlos harvests cassava is 35 minutes per 15 cassavas 15/35 = 0.429 cassava per minute

therefore, an equation that models the number of cassava (c) that harvest carlos in a time (t) is the following:

where t is the time in minutes.

this means that when 35 minutes have elapsed 15 cassava have been harvested, at 70 minutes 30 cassava have been harvested and so on.
