Answer:
20-5 × 5 + 3 × 6
20-25 + 36
Step-by-step explanation:
As QS bisects <RQT into 2 congruent triangles
therefore, <RQS = <SQT
4x-25= 2x+5
2x= 30
x= 15
<RQS = 4x-25
= 4(15) -25
=60-25
= 35

Answer:
see explanation
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180°
Subtract the sum of the given angles from 180 for A
A = 180° - (90 + 46)° = 180° - 136° = 44°
----------------------------------------------------------------
tan46° =
= 
Multiply both sides by 23
23 × tan46° = b, thus
b ≈ 23.8 ( to the nearest tenth )
-----------------------------------------------------------------
cos46° =
= 
Multiply both sides by c
c × cos46° = 23 ( divide both sides by cos46° )
c =
≈ 33.1 ( to the nearest tenth )
