Question

*The larger of two supplementary angles exceeds the smaller by 28°. Find the angles.*

1️⃣ 100° and 78°
2️⃣ 76° and 104°
3️⃣ 99° and 81°
4️⃣ 100° and 128°​

Answer 1

Answer:

4) 100 ans 128

The human skeleton is the internal framework of the human body. It is composed of around 270 bones at birth – this total decreases to around 206 bones by adulthood after some bones get fused together. The bone mass in the skeleton reaches maximum density around age 21.

Answer 2

let the angle be =

$x$

other angle (its supplement) =

$(180 - x) \: \: x + 18 = 180 - x$

$2x = 162$

$x = 162 \div 2 = 81$

other angle (its supplement) =

$180 - x$

$180 - 81 = 99$
