Answer:
To find h the altitude we use sine
sin ∅ = opposite / hypotenuse
From the question
AC is the hypotenuse
h is the opposite
sin 29 = h / 23
h = 23 sin 29
h = 11.1506
h = 11.00mm to the nearest hundredth
Hope this helps you
Answer:
honestly im trying to figure it out right now will get back to you when i figure it out.
Step-by-step explanation:
Answer:
x = 56
m∠WZX = 51°
Step-by-step explanation:
The measure of the exterior angle at a vertex of a triangle equal to the sum of the measures of the two opposite interior angles to this vertex
In ΔWZX
∵ The angle of measure 148° is an exterior angle at vertex x
∵ ∠XWZ and ∠WZX are the opposite interior angles to vertex X
→ By using the rule above
∴ m∠XWZ + m∠WZX = 148°
∵ m∠XWZ = (2x - 15)°
∵ m∠WZX = (x - 5)°
→ Substitute them in the equation above
∴ 2x - 15 + x - 5 = 148
→ Add the like terms on the right side
∵ (2x + x) + (-15 - 5) = 148
∴ 3x + (-20) = 148
∴ 3x - 20 = 148
→ Add 20 to both sides
∵ 3x - 20 + 20 = 148 + 20
∴ 3x = 168
→ Divide both sides by 3
∴ x = 56
→ To find m∠WZX, substitute x by 56 in its measure
∵ m∠WZX = 56 - 5
∴ m∠WZX = 51°
