Answer:
x=25°, y=18°
Step-by-step explanation:
Solved! Here is the explanation. As we have supplementary angles, we have a total of 180° of angles. Angle BXD is a right angle, so 2x+40°=90°. 2x=50°, and then we have x=25°. Now, to figure out y, we have to look at angle BXA. In this case, 5y=90°. y=18°. So, x=25° and y=18°. Hope this explanation helps!
Well u first have to eat a subway italian but it's is bomb
<h2>20cm</h2><h2>-------------------------------</h2>
<u>Step-by-step explanation:</u>
sides are 4cm, 8cm, 8cm ----( because isosceles triangle have 2 sides equal )
so, perimeter = sum of all sides
= 4 + 8 + 8
<h3> = 20cm</h3><h2>-------------------------------------</h2><h2>FOLLOW ME</h2>
Step-by-step explanation:
since x=2 and z=-2
4+4=8 [ because -2* -2=+4 ]
Using the Theorem of Pythagoras (a² + b² = c²)
Put in the values:
12² + 12² = 28²
Is it correct? (solve)
Nope! Because 12² + 12² = 288, and the square root of 288 is about 17, not 28.
The answer is no, 12cm, 12cm, 28cm cannot form a triangle.
