Show that the vectors a = 3i, b = 4 j and c = 3 i + 4 j form a right angled triangle.

If angle ywz = 17, what is angle wxy? ok so i'm confused on this because the triangles are congruent so that means they have the same measurement which would make wxy=17, but don't all triangles have total measures of 180 degress? ?me.

The base of a triangle exceeds the height by 7 centimeters. if the area is 400 square centimeters, find the length of the base and the height of the triangle.

Rachel is studying the population of a particular bird species in a national park. she observes every 10th bird of that species that she can find in the park. her conclusion is that the birds living in the park who belong to that species generally feed on insects. rachel's sample is . based on the sample she picked, rachel's generalization is . reset next
