Equilateral triangle<span> is a </span>triangle<span> in which all three sides are equal
</span>also 3 angles are equal and each angle = 60 degrees
so
2x - 4 = 60
2x = 64
x = 32
hope it helps
Given that
∠ABC and ∠CBD are complementary
Sum of complementary angle = 90°
⇒ m∠ABC + m∠CBD = 90°
⇒ 25° + m∠CBD = 90° [ Given that m∠ABC = 25°]
⇒ m∠CBD = 90° - 25°
⇒ m∠CBD = 65°
Hence proved
Answer:
<h2>x = 52.5 cm</h2><h2 />
Step-by-step explanation:
this is called a ratio and proportion or similar triangles
<u> 21 </u> = <u> 35 </u>
31.5 x
do cross multiply:
21 x = 31.5 (35)
x = 1102.5 / 21
x = 52.5 cm
