Answer:

A = (1/2)(7 units)(5 units) = (35/2) units^2.

Step-by-step explanation:

Call AB "the base" and recognize that its length is 7 units.  Call BC "the height" and recognize that its length is 5 units.

Then apply the area-of-a-triangle formula A = (1/2)(base)(height):

A = (1/2)(7 units)(5 units) = (35/2) units^2.

I needddd helppp please
Montano1993 [528]

Answer:

X=66°

Step-by-step explanation:

Because it is an isosceles triangle, the 2 missing angles are going to be the same size.

Subtract  48 from the total degree of the triangle which is 180.

180-48= 132

now you di ed that by 2 and you’ll know the missing angle.

132/2= 66

How many equilateral triangles with sides of 4 can fit into a larger triangle with sides of 2012
igomit [66]
The base measures 2012 if you divide that by four you get 503 trianles on the bottom and on the sides and each one gets one smaller until you get to one so 503+502+501,.... or 252+251(504) so the answer is 126,756 triangles in total because 1+503=504  2+502=504... when you get to 252 you just add that to itself so that is the odd one out
