5 0

Answer:

AB = 11.5mm

Step-by-step explanation:

let the hypotenuse be AC = 23mm

Angle of elevation = 30degrees

Required

Opposite AB

Using the SOH CAH TOA identity

Sin theta = opp/hyp

Sin 30 = AB/AC

Sin 30  = AB/23

0.5 = AB/23

AB = 0.5 * 23

AB = 11.5mm

Which of the following theorems verified that angle xyz is congruent too angle uwv?
icang [17]

Answer:

Option B.  AA

Step-by-step explanation:

we know that

Angle-Angle (AA) Similarity Postulate, states that If two angles of one triangle are congruent to two angles of another, then the triangles must be similar

In this problem

<em>In the triangle XYZ</em>

∠X=70°

∠Y=90°

∠Z=90°-70°=20° (remember that angle X and angle Z are complementary)

<em>In the triangle UWV</em>

∠V=20°

∠W=90°

∠U=90°-20°=70° (remember that angle V and angle U are complementary)

therefore

Traingles XYZ and UWV are similar by AA Similarity Postulate
