Answer:

x=7

Step-by-step explanation:

95+65=160

There is 360 degrees total in a quadrilateral

360-160=200

(15x-5)+100=200

15x+95=200

Subtract 95 from both sides

15x=105

x=7

In isoceles triangle the length of a leg is 17cm, and the base is 16cm. Find the length of the altitude to the base
Elan Coil [88]

This triangle has base 16 therefore the sides must be 17cm and 17 cm

When we make a altitude it divides it into two right triangles and there is a property in which the altitude of the isoceles triangle divides the base in 2 equal halves

So the side of the right triangle will be x , 8 , 17

Using pythgoreus theorem

x²+8²=17²

x = √225

x = 15

So the altitude is 15 cm
