Answer:
x+2y-14=0
Step-by-step explanation:
Divide both sides of equation by 3
Answer:
396°
Step-by-step explanation:
Difference = 357 -(-39) = 357+38 = 396°
Answer:
<h2>137°</h2>
Step-by-step explanation:
The pentagon RSTYZ is a regular polygon. Therefore all angles are congruent.
If m∠RST = 108°, then m∠STY = 108°.
We have the equation:
m∠UTY + m∠STY + m∠STU = 360°.
Substitute m∠STY = 108° and m∠UTY = 115°.
115° + 108° + m∠STU = 360°
223° + m∠STU = 360° <em>subtract 223° from both sides</em>
m∠STU = 137°
Answer:
Step-by-step explanation:
Given;
Δ QPR ≅ ∠ STR
i)
ii )∠ PRQ = ∠ TRS ( Both are 90° since QR ⊥ PT )
iii) ∠ RPQ = ∠ STR ( same side ratio from (i) )
Hence it is proved that
Δ PQR Δ TSR
