You find a triangle that has an area of 10 sq ft. the height of the triangle is 10 feet. what is the length of the base of the triangle?

Solution:

Given :

Area of triangle = 10 ft² Height of triangle = 10 ft

So, We have to find the Base of Triangle .

Area of triangle = 1/2*b×h, Where represents

B represent Base H represent Height

Step : Substitute those value in Formula;

Area of triangle = 1/2 × b × h

10 = 1/2 × b × 11

20 = 11 × b

b = 20/11

b = 1.81 ft

Therefore, Base of Triangle is 1.81 ft

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
