Answer:
p = 35
Step-by-step explanation:
Complementary angles sum to 90°
Sum the 2 given angles and equate to 90, that is
20 + 2p = 90 ( subtract 20 from both sides )
2p = 70 ( divide both sides by 2 )
p = 35
Answer:
<h3>
x = 3 units</h3><h3>
</h3>
Step-by-step explanation:
use Pythagorean theorem:
a² + b² = c²
where a = h
b = 8/2 = 4
c = 5
<u>plugin values into the formula:</u>
h² + 4² = 5²
h² = 5² - 4²
x = √9
x = 3
Set the length of the base as x, the two equal sides are then 4x each, so the perimeter is x+4x+4x=9x
Answer:
8 is the right answer
Step-by-step explanation:
in triangle swu,, wT bisect and perpendicular on su
so the triangle is isosceles triangle
therfore,Sw =, 8
