Answer:
x=14
Step-by-step explanation:
(7x - 1)° + (6x - 1)° = 180°
(13x - 2)° = 180°
13x = 182°
x = 182°/13
x = 14
Answer unavailable. If you wish to know the desired commission you must first display the commission rate.
Answer:
Step by step proof is given below.
Step-by-step explanation:
∠ABX = ∠XBC (given that XB bisects ∠ABC)
∠AXB = ∠CXB = 90° (given that BX is an altitude)
BX = BX (common)
Therefore,
ΔABX ≅ ΔCBX (ASA congruence theorem)
AX = CX (Corresponding parts of congruence triangles are congruent)
So, X is the midpoint of AC and hence BX is a median.
Answer:
See answer below
Step-by-step explanation:
RS ⊥ bisector of AB Given
AS ≅ BS Definition of ⊥ bisector
∠RSB is a right angle Given
∠RSB = 90° Definition of right angle
∠RSB & ∠RSA form a linear pair Definition of linear pair
∠RSB + ∠RSA = 180 A linear pair = 180°
90° + ∠RSA = 180° Substitution
∠RSA = 90 Subtraction
∠RSB = ∠RSA Substitution
∠RSB ≅ ∠RSA If equal then congruent
RS ≅ RS Reflexive
Δ RAS ≅ ΔRBS SAS
RA ≅ RB CPCTC (corresponding parts of
congruent triangles ≅
